Editorial

I would like to thank all those who sent their best wishes for

the new magazine. I would also like to thank everyone who

offered suggestions for improvements to the magazine and

website. Especially I would like to thank those who have

submitted articles for inclusion in future editions. They are

most appreciated. Thank you.

With the experience gained from the first issue we have made

some changes to the magazine. The fonts are now embedded in

the PDF files. We have found that this overcomes the

problems, which some readers experienced when viewing and

printing the magazine with Adobe Acrobat Reader 6. However,

this causes the file size to increase by 20%. Mindful of the long

download time experienced by readers using dial-up modems I

have divided the magazine into three files. In addition I have

provided a version with enhanced quality pictures which

broadband users might find preferable.

Several readers asked if we could arrange for them to be

advised when the next edition of the magazine is published. In

response to this request we have provided an option for readers

to register their e-mail address on our website. We will then

send an e-mail to announce the publication of each edition of

Model Railways On-Line Magazine with information about the

articles, which have been included. We undertake not to use

e-mail addresses for any other purpose.

In this edition we feature a large 00 gauge layout of Stafford

built by Harry Howell. The layout is based on the West Coast

Main Line in the transition period of the early 1960’s. Harry is

the Chairman of the British Railway Modellers of Australia, an

organization, which brings together followers of British practice

from all over Australia and New Zealand. The Prototype

Layout is Westerham, a sleepy S.E.&.C.R. branch line terminus

close to London. A scale plan of Westerham has been included

on page 11. By way of an alternative I have provided an option

for the plan to be downloaded as an A3 size sheet. At this size

the fine detail of my drawing is more clearly visible. Next

Graham Plowman completes the description of his layout based

on the South Devon Main Line. The selection of photographs

in this edition shows the layout in its 1984 guise, a time when

the resignalling of the South Devon Line was under way. For

the moment Ashprington Road retains its mechanical

interlocking and semaphore signals.

We have introduced two new items, which will become

regular features, a Hint ‘n Tips article and a Puzzle Picture. This

first puzzle picture was sent in by David Elliott of Victoria,

British Columbia. Thanks David it’s a good puzzle.

We have many ideas for interesting articles and hope to be

able to feature at least one high quality layout in each edition of

the magazine. I would be pleased to receive articles and

photographs on any subject, period, scale or gauge of interest to

modellers of the British scene. If anyone would like to have

their layout featured in Model Railways On-Line but does not

feel confident in writing an article then I can assist with

preparing the text.

The next edition of Model Railways On-Line Magazine will

be published on 1st August 2004.

STAFFORD

A large 00 gauge layout based on the West Coast Main Line

observed by closed circuit television.

Harry has undertaken extensive research

with the aid of many books, magazines and

site visits to recreate the buildings and

settings of Stafford in the early 1960’s.

Some compression has inevitably been

necessary and trains normally have a

maximum length of eight coaches. The

layout includes the junction to the former

Great Northern line to Uttoxeter and the

junction for the cross-country line to

Wellington and Shrewsbury. Norton Bridge

Station has been included and there is an

impressive representation of the four-track

main line northwards. The line to

Shrewsbury curves around the room to

Hoyle Station. Insufficient information was

available to construct an attractive country

station and Hoyle is purely fictional. The

name of the station is in memory of an old

modelling friend and is based loosely on

Yate and Charfield on the Midland line

between Gloucester and Bristol.

lower level and stairs give access to the

layout room. The difference in level is

sufficient to be able to pass comfortably

under the tracks without the need for a lift

out section. Nine storage tracks are

positioned high up in an adjacent office. At

the opposite end of the layout eight storage

sidings extend outside of the building into a

weatherproof area in which trains are

This magnificent layout resides in Sydney,

New South Wales and is the result of many

hours of meticulous work by it’s owner, Harry

Howell. It is housed in a purpose built building

and the visible area measures 33 feet by 12 feet.

The building is divided into two rooms, the

main layout room and a smaller one, which is

used as an office and for storage. The rooms are

on different levels. One enters on the

Period The period of the layout is set in the early

1960’s during the transition period from

steam and diesel to full electrification of the

West Coast Main Line. Motive power to be

seen on the layout includes red Duchesses

and green English Electric Type 4 diesels.

Also to be seen are some of the prototype

diesels of the period including ‘Kestral’,

DP2 and the prototype ‘Deltic’.

Overhead line gantries and cantilevers

have been erected along the main line but the

catenary and conductor wires have not yet

been installed. However, a little modeller’s

license is allowed with new electric stock

already appearing. Similarly, the Hornby

blue Coronation was irresistible. A full-

length train of nine coaches has been built

using Comet kits and overlays on Hornby

coaches.

three months to complete the task. The

result is a reliable layout with trains running

smoothly.

I would like to thank Harry Howell for

his kind assistance with the preparation of

this article and for allowing me the

opportunity to photograph his magnificent

layout.

The next Sydney area meeting of the

British Railway Modellers of Australia will

be held on Saturday 15th May at Harry

Howell’s home where members will be able

to see Stafford in operation. Prospective

new members are welcome and should

contact either the Membership Secretary

through the BRMA website at

www.brma.asn.au or Graham Plowman who

is the Sydney Area Organiser. Graham may

be contacted via the Editor on the Model

Railways On-Line website. ■

Trackwork Initially the layout was constructed using

Peco Code 100 track in the hidden sidings and

SMP Code 70 in the visible area. Ron Reilly

and Peter Swanson assisted Harry with the

construction of 45 hand built points. Jackson

wheels were fitted to all of the rolling stock and

the back-to-back wheel spacing was adjusted on

some 50 locomotives.

Within a year, wheel cleaning became a

major task. It was found that the flanges of

Lima and Hornby driving wheels were touching

the sleepers, causing imperceptible arcing from

momentary loss of contact between the wheel

tread and the head of the rail.

The task of re-wheeling all of the

locomotives was formidable. Trains were

running much better on the Peco code 100 track

in the hidden sidings and loops. Eventually the

decision was made to relay all of the track in the

visible area with code 100. It took a frantic

Westerham First in a series of prototype layouts

by Paul Plowman

History The branch line between Dunton Green on the South Eastern and

Chatham Railway main line and the market town of Westerham opened

in 1881. The line was single track throughout and just under five miles

in length. There was an intermediate station at Brasted, which had a

small goods yard and a halt at Chevening. There were no passing

places on the line. It was intended to extend the line to Oxted but in

the event the proposed level crossing across London Road was never

built.

Memories of the line My first acquaintance with the line was about 1954 on a cub scout

outing. The pack travelled from Grove Park to Dunton Green by

electric train. We crossed over to the branch platform where an

H Class 0-4-4T was waiting with a two-coach, former L.B.&.S.C.R.

push-pull set. The set was painted in crimson and I can remember a

second set being stabled in the run round loop in freshly painted green.

The train ran with the loco leading along the branch. From Westerham

Station we had to walk all the way up to Hosey Common where our

campsite for the day was located. Then in the evening we had to walk

all the way back again. As we arrived at Westerham Station the train

was waiting but this time the loco was at the Dunton Green end of the

train. Again it was a former L.B.&.S.C.R. push-pull set in crimson and

I can remember it being quite tatty. While we were waiting for the

connection at Dunton Green the ‘Arrow’ came racing through on its

way to Victoria. Regrettably that was the only trip I had along the

branch.

In the late 1950’s we used to go fishing at Tonbridge. The main

line was only electrified as far as Sevenoaks where one had to change

to steam. After the morning service the Westerham Branch train

worked empty stock to Sevenoaks and then formed a stopping service

to Tonbridge. Oh, the joy of travelling through Sevenoaks Tunnel with

dim lights and smoke swirling in through the windows! Those were

the days! On one occasion the journey home was behind a Q1 0-6-0.

Association was formed to fight the closure and leased the station

during 1962 and 1963 but it was all doomed to failure. Unfortunately

the Association comprised two factions. The local group who had

formed the Association were primarily regular passengers interested in

persuading BR to restore the service. Then there was a large wider

membership of enthusiasts who saw it as a chance to create another

Bluebell Railway (The Churchill Line). By the time the steam

enthusiasts and preservationists gained control of the Association it

was too late. Kent County Council wasted no time filling in the cutting

at Chevening for the Sevenoaks By-Pass. The section of line between

Chevening and Brasted is now under the M25 Motorway.

The membership had raised sufficient money to purchase an

H Class 0-4-4 tank engine and this loco can now be seen on the

Bluebell Railway. Two members purchased coaches for use on the line

and these can now be seen at several locations around the country.

The Layout Westerham was a simple terminus with a single platform 290 feet in

length, just long enough for five coaches. The run-round was about

480 feet, long enough to clear eight coaches. However, if the loco was

to shunt into the yard it was possible to run round an 800 foot train.

The station had all the usual features we find in a small terminus; a

small goods shed, an end loading dock, a yard crane, a signal box, a

water tower, and an engine shed.

A model could be built in 4mm scale on two feet wide baseboards.

_______________

My grandparents retired to Polegate near Eastbourne and once a

month during the late 1950’s my brother and I had to endure a trip by

car from South London. The route took us via Westerham and over the

Ashdown Forest. Occasionally we saw a train as we passed Hartfield

Station on the Tunbridge Wells West to East Grinstead line. On the

return journey we would stop at Westerham to use the facilities

provided by the Crown Hotel. The Hotel is just across the road from

the station. I can remember seeing the train waiting there on dark

nights and being able to look right through the booking hall to see the

dimly lit carriages. Looking at the plan accompanying this article, the

doors of the booking hall are not in line with each other but when

viewed from the toilets outside the Crown Hotel there is a sight line

right through the building!

Closure The line eventually closed on 30th October 1961. At the time there

were 200 passengers a day using the line. The Westerham Railway

If space was available for three feet wide boards this would provide

room to model the coal merchants area and a low relief frontage to the

Crown Hotel. The overall length from the home signal to the buffer

stops would be 16ft 6in without compression. The three turnouts in the

passenger carrying line were all C9’s with straight switch planing and

the turnout by the loco shed was a B8. The crossover in the yard

appears to have been made up from a B7½ to a B6. By using Peco

large radius points, which approximate to an A6½ turnout the length of

the model could be compressed. by about 18 inches. By shortening the

platform to four coaches, reducing the shunt neck and moving the

home signal closer a further two feet could be saved, bringing the over

all length of the model down to 13 feet.

At the time of closure the track on the branch was still exclusively

bullhead.

12 MODEL RAILWAYS ON-LINE

ASHPRINGTON ROAD – Part 2

A 00 layout based on the Western Region Main Line between Exeter and Plymouth

By Graham Plowman

Time has been passing and it is now 1984 on the South Devon Railway

A paper template of the layout

The next step was to build a paper

‘model’ of the layout. For this I used sheets

of newspaper held together with sticky tape

and cut them to the shapes of the boards.

These were laid out on the floor of the

railway room to give a full-size

representation of the layout. This is also a

good technique for refining the board shapes.

I had worked out the board shapes

mathematically, but it wasn't until I created

the newspaper templates that I found that

one of my calculations was incorrect and

needed revising. This could have been a

costly error if I had been constructing with

timber!

With the newspaper templates on the

floor, I laid track loosely on them to get an

idea of how the layout would appear.

Fortunately, the track fitted on the ‘boards’

without any problems. The paper templates

were also used to determine the position of

board bracing to avoid conflict with point

motors. Building the baseboards The baseboards were built using 12mm

plywood because this material stands up to

changes in temperature and humidity much

better than the traditional chipboard and 2-by-1

method. I had also obtained a large amount of

Dexion (the giant Meccano used for shelving

racks) to form the bracing beneath the boards.

With 12 boards to build, construction took a

couple of months. The boards are held together

with bolts and each joint is supported by a pair

_________________

of legs. When all of the boards were

completed and erected, they needed to be

levelled. I used a builder’s spirit level and

found that I needed to make a number of

adjustments to ensure that all of the boards

and particularly the joints, were level.

After levelling, the track layout was

drawn out on the surface of the boards.

Large curves were marked out using a

measuring tape. I positioned my folding

workbench in the middle of the layout and

held a piece of timber in a vice with a nail in

the top. A tape measure was hooked on to

the nail and the arc marked out on the

boards. This was done for curves at both

ends of the layout but proved more difficult

on the ‘London’ end because the board level

is 20icm lower for the viaduct. Years ago,

my father was lucky enough to obtain some

railway drawing curves, which were being

disposed of by a drawing office. These have

been invaluable.

MAY 2004 13

Viaduct Construction I have always felt that having model trains

going over a bridge or viaduct adds an extra

dimension to the appearance of a layout.

Before commencing construction, I

undertook some research examining pictures

of viaducts in Devon and Cornwall. The

purpose of this was to identify the little

details and techniques used in building the

prototype that are so often missed in models:

There is rarely much distance between

the top of the arches and the underside of

the track. From the underside of the

sleepers to the top of the brickwork can

be as little as six inches of ballast!

The locating holes used to position the

timber formwork used during

construction are often missed.

The stonework ‘style’ often changes

between the pillars and the viaduct

arches.

Many viaducts have refuges for track

staff to stand in safety when a train

passes.

Some viaducts have fencing instead of

parapet walls.

Those with fencing have low parapet

walls usually only just high enough to

retain the track ballast from falling off.

Most viaducts (in the UK) have some

form of guardrail device to restrain a

derailed train (see my article on Guard

Rails in the first edition. Ed.).

I chose to base my model on Clinnick

Viaduct, which is a six-arch structure on the

6imile bank between Doublebois and

Bodmin Road in Cornwall. The structure is

straight, so some modeller’s license has been

applied by building the model to suit a curve

on my layout.

Clinnick Viaduct is a very good example

of the standard design of viaduct used in the

Devon and Cornwall area, representing a

tidy, yet interesting structure. Building the

model turned out to be a mammoth task.

The basic structure was constructed using

plywood, nailed and glued together. It is a

complete self-contained unit, which can be

removed from the layout. It has a ‘novelty’

feature in that because there would be a

point motor located between two of the

arches, there is a cable ‘pull string’ that can

be used to pull cables up and down the inside

of the pillar. The structure was covered with

Polyfiller. This was left for two days to dry

before starting the carving of the stonework.

I used a modelling drill with a mini

‘countersink’ and this worked very well.

However, the carving process took an

inordinate amount of time to complete to the

point where I almost lost interest! The moral

here is to build a smaller viaduct! Capping

stones were made of balsa wood. These

were attached first and then rubbed down to

shape. Side fencing, made by Faller has been

purchased but not yet fitted.

Preparing the trackbed I decided from the outset that all of the

main running tracks would be canted (tilted)

on curves. To achieve this requires a

_______________________

different approach to construction from the

conventional method of laying track directly

onto the board surface. I used a layer of 6imm

plywood to form a sub-base for the trackbed.

At the outer edge of the sub-base, on curves, a

1icm wide strip of 3imm thick hardboard was

tucked under the edge to provide a tilt. The

assembly was held in place by screwing to the

main baseboard.

Where curves pass through a transition into a

straight, the construction becomes more

complicated requiring the hardboard to be

progressively increased, or reduced in thickness.

Suffice to say that prototype geometry has been

adopted. This was achieved by using

professional railway alignment design computer

systems and plotting the plans to 1:76.2 scale

for laying directly onto my baseboards.

Because we have to make significant

compromises for the radius of curves on our

________________

model layouts, all of the transitions on my

layout correspond to the minimum length

permissible on the prototype. This scales to

about 26cm long, or about the length of a

coach. The 3mm packing under the trackbed

described above, creates an angle of super

elevation, which is equivalent to 2 inches of

cant on the prototype.

I have chosen to have both tracks canted

in the same plane as this significantly

simplifies construction, and enables

crossovers to be located on curves. There

are several other possible configurations for

canting pairs of tracks. The emerging

standard appears to be for the two inside

(sixfoot rails) to be at the same level and for

the outer (cess) rail of the outer track to be

raised through transitions while the inside

(cess) rail of the inner track is lowered

through transitions.

14 MODEL RAILWAYS ON-LINE

The electrical system Once a trackbed has been prepared, there

is a great temptation to start laying track.

However, this can lead to all sorts of

problems such as the track having to be

pulled up to fit insulating joints or the use of

rotary saws to cut rails to create isolating

gaps. It becomes necessary for wires to be

soldered to the sides of rails, resulting in

unsightly solder globules and melted plastic

sleepers, which destroy any possibility of

realism. Planning beforehand prevents all of

these problems.

I designed the electrics in the form of a

feed diagram. This included all isolating

sections, overrun dead-sections, signal

run-past sections and switching between

controllers. Using this diagram, I would cut

the rails appropriately and fit isolating

fishplates where required.

Although supplied as ‘live frog’ turnouts

which can be connected up and used ‘as is’,

the Peco codei75 turnouts are designed so

that they can be re-wired to meet the

modellers’ requirements. Essentially, the

switch rails can be connected electrically to

the stock rails and isolated from the crossing

vee. This enables the vee to be fed

_____________

separately and not to rely on the contact of the

switch rails. To prevent any possibility of

shorting on the backs of the switches caused by

out of gauge wheels, I have rewired all of the

turnouts to provide separately switched feeds to

the crossing vees. Point motors are mostly Peco

and use the Peco switches. In certain situations,

Seep motors were later used as these proved to

have much more reliable switches.

Signals are GW lower quadrant semaphore,

using mechanical relays. Since the layout is

also required to represent the BR blue period,

the use of semaphore signals dates it to 1984 at

the latest. After this date Exeter Control Centre

came into use and all signalling in the area was

replaced with colour lights.

Track laying Track laying commenced once the electrical

diagram had been completed. Track was glued

down using either Evo-stik or PVA after the

appropriate wires had been soldered to the

undersides of the rails.

Computer control system As previously mentioned, the layout is

computer controlled. The system controls all

movements of points and signals but it

________________

does not drive the trains. Trains are driven

using conventional Gaugemaster WS

handheld controllers.

I have used the ‘Remote Panel Control’

hardware system available from the Model

Electronics Railway Group (MERG). The

core of this system is a control board, which

connects via a cable to the RS232 port of a

PC computer. A number of other boards

connect to the control board to form a stack.

There are boards containing 8 relays, 32

logic level outputs, 32 logic level inputs and

8 track circuits.

The relays are used to control track

section switching between controllers and

switching of isolating sections. The logic

level outputs are used for controlling the

point motor modules and signals. The signals

are mechanically powered from relays

connected to the logic level outputs.

Using this system, there is no need for a

control panel – on this layout it is a computer

screen.

Computer software The software used is the ‘Solid State

Interlocker’ (SSI) software from

GPP Software.

HST’s pass at Ashprington Road Station

MAY 2004 15

The website address is

www.gppsoftware.com/ssi/ssi.asp. This is

the only software available, which represents

British practice. SSI simulates modern IECC

computer control systems used in UK

signalling centres and looks and operates

like the real thing, including graphics and the

mouse operation of Entry/Exit route setting.

The SSI software supports a fully

signalled and interlocked layout and these

capabilities have been fully utilised..

Signalling Signals are constructed from Ratio kits

suitably modified. They are all fully working

including ground signals and are operated

from the mechanical action of relays

controlled by the computer system.

Scenery

Once the signalling was completed, a

start was made on the construction of the

scenery. Wood-fibre insulation board was

used for the formers, which was cut to suit

the profiles of embankments and cuttings.

The gradient of cutting and embankment

slopes is 1 in 1½. This is about the

maximum value for normal soils. Rock can

be steeper and clay is shallower. I made up

a 1 in 1½ triangle from card as a template for

slopes.

The scenery formers were covered with

chicken wire. Layers of newspaper soaked

in plaster have been laid over this to create a

reasonably thick surface with some strength.

When dry, this was all painted in a light

green, which can be seen in the photographs.

This is a base colour for the scenery and will

later be covered with scenic materials.

Buildings ‘Ashprington Road East Signal Box’ is a

Ratio ‘Highley’ kit and the west signal box

is from Hornby. The Hornby model is of

Hagley Signal Box and their GWR

footbridge kit is from the same location. I

will be installing the footbridge at a later

date but temporarily I am using an

Airfix/Dapol kit footbridge.

Other buildings to be constructed will

include a stationmaster’s house, which will

be made from Linka. A goods shed and the

abutments for the bridge over the railway at

the western end of the station will be

constructed using the same techniques as I

have described for the viaduct. The steel

plate girders of the bridge are MDF and will

be detailed with plastic and metal strips. The

tunnel mouths are from Merit.

Rolling Stock My collection of rolling stock falls into

two distinct periods, late BR steam with

early diesels and the blue period of 1984.

Steam locos are a mixture of Bachmann,

Hornby and Mainline with early diesels from

Bachmann, Mainline, Lima and Heljan. All

have been weathered. The 9F and the

Britannia are hand built. The construction of

the Britannia is featured on page 16 of this

edition of the magazine.

Diesel locos in the blue period are

from Mainline and Lima.

Coaching stock for the steam era is

predominantly Bachmann MK1’s with a few

period they are mostly Hornby and Lima.

Wagons are a mixture of Bachmann,

Replica, Hornby and Dapol.

16 MODEL RAILWAYS ON-LINE Having successfully completed building a

BR 9F locomotive, I decided that I wanted to

model a Britannia 4-6-2 Pacific as my next

project.

Research I purchased the Ian Allan book ‘BR

Standard Pacifics In Colour’ (ISBN 0-7110-

2264-x). This is one of a series of several

dozen books published by Ian Allan, all of

which contain 100% colour pictures of BR

Steam from the 1950’s through to the

1960’s. These are all excellent books and

invaluable material for the modeller of the

early BR period.

The Britannias were the first of the BR

Standard designs, being built between 1952

and 1954. Their design was the

responsibility of Robin Riddles CBE and his

team who included Roland Bond and

Stewart Cox. Many texts have been written

as to the reasoning behind the building of the

BR Standards, so I will not cover this here,

suffice to say that there was a need for a

class 7P express passenger locomotive.

The first of the new locomotives was

named ‘Britannia’ by the then Minister of

Transport, Alfred Barnes at Marylebone

Station on 30th January 1951. When Robin

Riddles renamed ‘Britannia’ after its original

restoration on the Severn Valley Railway in

May 1978, he revealed the reason for the

name as coming from the coat of arms of the

London and North Western Railway, which

had Britannia included within it. He also

started his career with the LNWR. He

believed that the name would be fitting for

both his first locomotive and for his new

(and last) employers.

Building a Britannia Class 7P 4-6-2

By Graham Plowman

Graham describes how he built a model of Morning Star

Two of the class, No.70000 ‘Britannia’ and

No.70013 ‘Oliver Cromwell’ are preserved.

No.70000 has been fitted with dual air and

vacuum brakes fitted while in preservation.

The Britannias were allocated to the various

regions as follows: Locos 70000 to 70014 were

allocated to Stratford except 70004 (William

Shakespeare) and 70014 (Iron Duke) which

were seconded to the Southern Region for use

on the ‘Golden Arrow’ service. These were

named after historical characters. The second

batch, 70015 to 70029 were allocated to the

Western Region. These were named after GWR

broad gauge engines. 70030 to 70034 went to

the Midland Region and were named after poets

and writers. 70035 to 70043 were named after

writers and historical figures and went to the

Great Eastern. 70043 and 70044 were allocated

to the Eastern Region but went on loan to the

Midland when new, together with the rest of the

class up to 70049. This batch bore the names of

military gentlemen with the exceptions of 70046

‘Anzac’, 70047 the only Britannia which was

never named and 70048 ‘The Territorial Army

1908-1958’. 70048 had the only name in the

class which ran to two lines on the nameplate.

70049 to 70054 were named after Scottish

waterways, these all being allocated to the

Scottish Region.

Like many new designs, the Britannias

suffered a number of teething problems,

including breakage of cast iron piston heads.

The cause was identified in the dome where the

level of steam intake was only 11¾ inches

above boiler water level. This necessitated the

fitting of a higher dome to prevent excess water

overflowing from the boiler being carried down

into the cylinders. A number of coupling rod

and pin problems occurred in addition to a

tender parting from its loco!

Perhaps the most well known problem with

Britannias was on the Western Region, which

led to changing the design of smoke deflectors

fitted to most of the class. No.70026 ‘Polar

Star’ derailed at Milton between Steventon and

Didcot with the loss of 11 lives and 157 injuries.

Permanent way relaying had necessitated slow

line running but the driver failed to negotiate a

crossover at the required 10mph and did so at

50mph, taking the entire train off the rails.

_________

The subsequent enquiry blamed a

combination of left-hand drive, bad weather,

poor visibility, a fireman unused to the road

and the handrails on the smoke deflectors as

the cause. The enquiry recommended

changes to the smoke deflectors. The

Western Region over reacted, removing the

original handrails and covering the smoke

deflectors in hand holes, whereas the

Midland Region made a much tidier

two-hole modification.

Britannias were paired with a number of

tenders. The first 24 locos of the class and

70039 to 70044 had BR1 tenders, 70025 to

70029 had BR1A tenders and 70045 to

70054 had BR1D tenders.

The first Britannia withdrawn was

No.70007 ‘Coeur de Lion’ in June 1965. The

last was 70013 ‘Oliver Cromwell’ on

12th August 1968.

Planning the project I model the early 1960’s period on the

Western Region and chose to construct a

Britannia allocated to that region. This

determined the tender paired with the model

and also the smoke deflectors. I think the

Western Region spoilt the appearance of the

Britannia smoke deflectors, so I chose to

model the ‘odd one out’, No.70021

‘Morning Star’, which did not have these

modifications. I have a picture of ‘Morning

Star’ taken in September 1967 shortly before

withdrawal and it still had the original smoke

deflectors most likely because it moved to

the Midland Region before it was modified.

Other than this, my model would be a

standard Britannia with all the normal

fittings and nothing out of the ordinary.

The following components were used in

the construction of the locomotive:

Hornby Britannia body. I had an

unpainted body from the factory without

fittings.

Crownline detailing, smoke deflectors,

handrails, sprung buffers, all fittings,

pipework. Etc.

Comet Brass chassis kit.

Gibsons RP25 wheels.

Portescap motor.

Airfix kit 9F tender, to be extensively

modified.

Romford Screw link couplings.

CGW nameplate and smoke box

numberplate for No.70021, ‘Morning

Star’.

DJH Britannia trailing pony truck. Comet

recommend the Hornby version, but it

lacks so much detail when compared with

the DJH version.

Genuine coal for tender.

PC Models transfers and lining.

The model after fitting the Crownline components

MAY 2004 17

Preparation A number of construction issues needed

to be resolved before I started building.

Electrical pickup would be via Gibson’s

plunger pickups on all driving wheels.

Tender pickup would also be provided using

conventional ‘wiper’ strips. The motor

location was chosen in the firebox and it

would drive the axle of the rear driving

wheels. Attachment of the body to the

frames would use the slot in the Hornby

back head and the screw hole under the

smoke box. Chassis frame spacers would be

suitably positioned, taking into account the

location of the plunger pickups.

Construction Work commenced on the locomotive

chassis. The Comet chassis needs to be

soldered together and when complete, it

provides a nice firm frame. I find the Comet

chassis to be very accurately made and they

fit together squarely very easily – well done

Comet!

I decided not to compensate the chassis.

I have mixed feelings about compensation.

On the one hand I feel that if you need

compensation in OO then your track can't be

laid very well and it can cause clearance

problems with coupling rods behind cross

heads. On the other hand, not everyone

builds 100% level track so my model could

potentially be prone to derailing. I later

found no problem at all.

It was important to make sure that all

wheels touched the rails and the whole

assembly was dead square.

Fitting the body to the chassis was quite

straightforward as the Comet chassis is

purposely made for the Hornby body. I

should note at this point that over the years,

Hornby have modified the Britannia body

since its original Tri-ang days. Earlier

versions have a higher buffer beam relative

to the boiler-side running plate and I believe

they were also a different length. The Comet

chassis will only fit the later body style, i.e.

the current version, which appears to be

accurate in basic dimensions.

The only problem I found is that there is

no provision on either the Hornby body or

the Comet chassis for a tender coupling.

_____________

I therefore improvised with an Airfix kit 9F

coupling. The boiler was filled with lead

weighting.

Bodywork The Hornby body requires relatively little

preparation for use when purchased in its

unfitted and unpainted form. I used all of the

Crownline detailing pack components and

fittings, in some places replacing Comet

components, as the Crownline components were

more detailed.

One nice feature is that the Crownline pack

comes with some large chunks of metal, which

fit behind the firebox sides and under the

footplate. Their purpose is to give the firebox

some ‘body’. This really does bring the

character out over the Hornby model. It makes

the firebox look as though it is solid right

through, giving a chunky impression and

making it look very realistic.

Previously on my 9F I had chosen not to use

the Crownline firebox-top pipe work but

______________

on this model I decided that I would use it

even though it is slightly over scale.

Looking at pictures of Britannias, I noticed

that the mass of pipe work all over the

firebox is very prominent and it looks

extremely untidy. I decided that this ‘image’

could be achieved with slightly over scale

Crownline components and proceeded to use

this method with very realistic results. I also

used some copper wire in places where

Crownline omit components.

The chimney and dome were replaced

with brass and white metal components

respectively. I used many other Crownline

parts to detail the body such as handrails,

knobs, smoke deflectors, boiler top feeds,

smoke box door fittings, steps, buffers and

brake pipes, etc..

The pipe work on the side of the firebox

is such that it restricts the movement of the

pony truck. I fitted the pipe work so that the

locomotive would negotiate the tighter 2’-6”

radius of a Peco large radius curved turnout.

To make the loco negotiate anything sharper

would have meant omitting the pipe work

altogether and resulted in a model lacking in

detail!

Fortunately I have no curves on my

Ashprington Road layout, which are sharper

than the 2’-6” radius mentioned.

Valve Gear This is supplied by Comet as a nickel

silver sheet with dozens of parts. I cut out

the required parts and soldered most of them

together. When using Gibson’s wheels, one

has to be careful with the heat from a

soldering iron near the plastic spokes.

Gibson’s wheels are designed for their own

system of crankpins which I also used. I

find these components easy to work with and

they look better than Romford equivalents.

I can’t get on with laminated coupling

rods. I find them incredibly difficult to

_________

solder together. I would prefer solid/ cast

nickel silver components instead.

Fortunately, only the coupling rods were

laminated on this model. The Britannias

were built with fluted coupling and

connecting rods but in later years, many had

their coupling rods replaced with flat non-

fluted rods.

The Tender This required the most work. The

Britannia has a BR1 tender, which is very

similar in appearance to the BR1G used by

the 9F’s, so I chose to use a tender from an

Airfix 9F kit. I have since found that Comet

make a suitable tender kit in brass and white

metal!

I prepared all the parts, cut off handrails,

replacing them with brass handrails and cut

off the plastic ladder on the back. I later

soldered up a ladder from copper wire as a

replacement.

The tender was weighted with two lead

sheets along the insides. Gibson’s wheels

were fitted on Lima axles, running in Peco

bearings. I had previously used this

combination on my 9F but unfortunately it

did not work very well on this model.

______

Lining was achieved using PC Models

press-fix lining. I find this easy to work with

and it gives very fine results. After fixing, I

immediately varnished the loco and tender

body to prevent the transfers coming off. I

hand painted the lining on the sides of the

footplate. Transfers would not have stuck to

this. I am fortunate to have reasonably

steady hands, so the lining came out quite

well. Hornby also hand paint this part of

their models.

Weathering Next came the task I enjoy most,

weathering. I think the Carrs modelling

powders are excellent for this and provide an

easy way to achieve a very realistic finish. I

would always recommend obtaining colour

photographs of the subject before attempting

any weathering. If you make a mistake with

Carrs powders, a damp sponge easily takes

you back to the start. I apply the powders

using an old toothbrush and find that I don't

need to 'fix' them afterwards. However, an

artist’s matt spray varnish can be used if

required.

I decided that my Britannia would only

have a light dusting, giving a finish that

looks as though the loco has been in service

but has been relatively well looked after.

For this purpose, I used a combination of a

few brown coloured powders in extreme

moderation. Colour photos provided

excellent examples for matching of colours.

The principal effect required was to obtain

an ‘ash’ appearance all around the underside

of the firebox and a general ‘ash and brake

dust’ appearance on the chassis.

Running in Having built the locomotive, it needed to

be lubricated and run in. Unfortunately, I

had a few teething problems with the driving

wheel quartering and ‘wheel wobble’, which

required the wheels and coupling mechanism

to be dismantled several times. Once fixed,

the Portescap motor manages to power this

model very smoothly. I became somewhat

disappointed with my Bachmann ‘Mere

Hall’ when it did not match up to the smooth

running of the Britannia! ■

I could not get the wheels to run true on the

axles. I think they probably came from a faulty

batch. I obtained replacements, which ran

better. They are still not perfect and I am not

entirely happy with the tender chassis. It doesn’t

sit totally square on the rails in certain situations

and the wheels still wobble slightly, although

not noticeable to the untrained eye. At some

point in the future I am planning to replace the

tender chassis with the Comet kit, which has

inside bearings.

The tender was filled with coal, which was

fixed using the standard method of watered

down PVA with a drop of washing up liquid to

break the surface tension.

Painting I painted the whole locomotive in BR

Standard Loco Green using Railmatch paint.

This gives a nice finish. Later I added some

Carrs Modelling powders for weathering. I

used Woodhead transfers for the numbers and

coat of arms on the tender - the Britannias had

the same left-facing lion on both sides.

Humbrol Matt Black was used extensively.

Pipe work and coupling rods were painted using

a mixture of Humbrol Scenic Track colour, with

Railmatch ‘oily steal’ and ‘frame dirt’.

The finished model

Hints ‘n Tips: Repairing Heljan Hymek Buffers by Graham Plowman

Unfortunately my Heljan Hymek arrived

with a broken buffer.

Repair was not a case of simply gluing

the broken part back on because it was

missing from the box. Firstly a small

amount of Super Glue was placed on the

broken edge of the buffer. It was then built

up with Humbrol Model Filler, which mixed

with the Super Glue to obtain a solid

attachment. Humbrol Model Filler is a paste

with a consistency rather like toothpaste and

is very hard when set. It is intended for

filling cracks and holes in models. When the

filler is set, a file can be used to shape the

buffer and after painting, the model looks as

good as new. ■

20 MODEL RAILWAYS ON-LINE

The Model On opening the box, the first thing that is

noticeable is the amount of detail on the

model. Removal from the usual polystyrene

tray is straightforward. The only extra part

in the box is a small packet containing

detailing pipe work for the rear buffer beam.

Moulding and painting is very crisp all

over and the model has certainly captures the

overall image of the prototype very well,

including rivets. The cab is fully detailed

including back head and driving controls.

This is possible because the motor is

mounted in the firebox. The buffers are

sprung and are of a consistent height above

rail level at both ends of the locomotive.

Couplings are fitted into NEM pockets,

which are attached to the pony trucks. The

axles on the pony trucks are completely

unrestrained in sideways movement and can

actually slide 3mm, although when running

they appear to centralise themselves.

Coupling tension causes centring although

propelling might cause the axles not to be at

right angles with the rails. The author

suspects that the pony trucks have been

designed this way to afford increased

sideways movement of the coupling on

curves but feels that it is quite unnecessary.

Even on moderate curves it is noticeable that

the guard irons are not always in line with

the wheels and rails. The irons are set at

16.5mm gauge. This movement is far too

much and could be remedied by the fitting of

washers.

The sample under review unfortunately,

suffered from a number of quality control

problems, which could easily be remedied by

most modellers. The model is supplied with

brake rigging already attached but on this

model it was not fitted correctly and was

Bachmann’s latest release comes in the

form of an ex GWR 45xx Class 2-6-2 prairie

tank, a very notable omission from the

Western market space, especially since the

demise of the similar Lima version.

Prototype History The 45xx was a development of the

earlier Churchward 44xx Class 2-6-2T

locomotives. It was almost identical to the

44xx, the only major difference being the

larger 4’-7½” driving wheels and the drop

end curved arrangement of the running plate

profile from No. 4534 onwards. The

increased driving wheel size made the 45xx

a generally more useful loco because of the

possible increase in speed. The 45xx was

widely used on branch lines, both

______________

Review of the Churchward 45xx from Bachmann

By Graham Plowman

for passenger services and for goods trains.

Built originally at Stafford Road Works,

Wolverhampton between 1906 and 1908, the

first batch of 45xx locomotives were

numbered 2161-2180 and later renumbered

4500-4519. The second batch, Nos. 2181-

2190 was constructed at Swindon from 1909.

Renumbering to 4500-4574 took place in

1912.

Five batches of 45xx were built at

Swindon until construction ceased in 1924.

They were superseded by the 4575 Class

three years later. Withdrawals commenced

in 1950, primarily due to the age of some of

the earlier examples. Fortunately, we can

still see the 45xx as Nos. 4555, 4561, 4566

and 4588 have been preserved.

hanging loose. The lamp irons above the

front buffer beam are not straight. Probably

the most noticeable problem is the number

plates on the coal bunker sides, which are

printed (even though the prototypes were

castings) and they are not horizontal. They

lean downwards towards the back of the

locomotive. The careful observer will note

that even allowing for perspective, it is

possible to see this problem in the

photographs published in the Bachmann

2004 catalogue. The slide bars have not

been fitted correctly. On one side, they lift

up towards the cab and on the other they

drop down towards the track. They should be

level. The crosshead and vacuum pump

casting looks a bit crude. Coupling rods are

realistically darkened and the overall finish

of the model is very well done. There are no

mould joins along the top of the boiler.

Instead, they are very fine and cleverly

aligned with the handrails along the side of

the smoke box so as not to be noticeable.

From No. 4520 to 4554 the class was built

with copper capped chimneys and from

No. 4555 onwards they were built with cast

iron chimneys without a copper cap. All of

the 4575 Class had cast iron chimneys. The

model of No. 4560 correctly portrays a cast

iron chimney with no copper capping. A

minor point, but the whistles are too far

forward from the cab by about 2mm

according to scale drawings.

This model is NOT designed for the

fitting of screw couplings. The body

retaining screws are located directly behind

the buffer beam, in exactly the location

where the shank of a hook would pass

through and where the coupling spring

would be located. It is concerning that the

author recently reviewed a new model from

another manufacturer, which was also

designed not to permit the fitting of screw

couplings. There seems to be an incorrect

assumption that the provision of NEM

pockets means that nobody will want to use

other coupling systems! The footplate and

buffer beams are metal.

Performance Straight out of the box, this loco ran

extremely smoothly in both directions.

Electrical pickup is via wipers on the backs

of the driving wheels only. This is contrary

to a review in one of the mainstream

magazines. The author believes that the

reviewer mistook the copper/bronze pony

truck springs as pickups. There were

certainly no pickups on the pony trucks of

the model in this review and there were no

problems with electrical pickup.

After a short period of running it could be

seen that the model had a distinctive ‘limp’

when running in the reverse direction. This

wobble needed close observation to be seen.

Further inspection revealed that the rear

driving wheel on the driver’s side was not

concentric on its axle and it could be seen

that the flange varied in depth as the wheel

revolved. A check of the wheel tread

removed some excess black paint, but this

did not resolve the problem. Closer

inspection of the wheel treads leads the

________________________

author to believe that the tyres on this loco may

be cast and not machine turned as on other Blue

Ribband models. This was evidenced by the

treads on one side having pitted surfaces,

blemishes and a couple of nodules reminiscent

of the early cast wheels, which Bachmann used

to fit. Or possibly the material used was not of

a quality standard.

All wheels have the correct number of

spokes. Drivers are 18.48mm in diameter. The

prototype drivers were 4’-7½”, which equates to

18.49mm – so are spot on. Pony wheels are

12.6mm, equating exactly to the prototype

3’-2”. Back to back wheel measurement is

14.3mm.

The haulage capability is extremely good

due to the weight of the model. It is very easy

to take apart by removing two screws located

behind the buffer beams at each end. The

chassis is very neat and tidy with a centrally

mounted motor driving the centre axle through a

worm and gear train. Of particular note is that

when assembled, it is not possible to see the

mechanism, because it is effectively sealed in

due to the weights located in the side tanks

aligning with the chassis block. This is a very

good idea and keeps dust and dirt out of the

mechanism.

Once dismantled, the obvious omission

inside is a ‘plug and play’ DCC socket. This

____________________

model has a small PCB, which requires

two coils to be removed and wires to be

soldered to fit a decoder. When one

considers that Bachmann has now entered

the DCC market in the UK with its own

system and has been pushing the merits

of DCC for some time, it is really

surprising that this latest addition to their

range doesn’t have a DCC socket

facility, especially when there is ample

room inside for such a fitting.

Verdict Although the model under review had

a number of minor quality control

problems, most of them could be fixed by

the average modeller. The appearance of

the model is excellent. It is very well

finished and accurate in all the major

dimensions and certainly portrays the

image of the prototype in every way.

It is a very useful addition to any

GWR or BR(W) layout as these

locomotives were widespread in their

operation, especially on branch lines.

As with any model purchased these

days, the advice is to ask your dealer to

test run the model for you before buying.

Picture’ feature. Readers are invited to

submit their curious and puzzling

pictures to the Editor. The correct

answer or explanation with revealing

pictures will be published in the next

edition. I would request that those who

might know the answer do not tell

everyone by posting it in an e-group.

Please send your answer to the Editor

via our website at

This puzzle picture of a single line

tunnel was sent in by David Elliott of

Victoria, British Columbia, Canada.

It certainly has architectural character,

which would make an interesting

model. Readers are invited to identify

this tunnel and tell us a little about its

history. To enable us to judge the size

of the structure, David tells us that the

lady in the picture is his wife who is

5ft 2in tall.

Puzzle Picture: Can you identify this tunnel and tell us a little about its history?
