RCS Developments

Technology Migration

9

›Trends in UK Conventional Signalling

›Relay Based Interlockings Computer Based Interlockings

›Track Circuits Axle Counters

›Localised Control Centralised Control

›Filament Lamp Signals LED Signals

›Colour Light Signals In-Cab Signalling

›Intermittent Train Protection Continuous Speed Supervision



Reasons for Technology Migration

10

It’s all about the money

Getting more performance and safety for less investment

Reducing the cost of infrastructure renewals

Decreased maintenance costs

Optimising the cost of mid-life enhancements

Increased automation – lowering operational costs

Improved safety



In-Cab Signalling Trends

11

›CBTC ›Adopted by metros around the world for both greenfield and brownfield upgrades

›No equipment standardisation between suppliers

›Clients are tied into the supplier for the lifetime of the system

›ETCS ›Standardisation imposed to achieve interoperability

›Mandated by law for mainline railway upgrades in the EU, but adopted elsewhere too

›Standardisation limited to constituent sub-system interfaces

›Requires country specific operational design

›PTC ›Communication based ATP system mandated by American law for freight and passenger

›Deadline for implementation extended to end of 2018 (3 year extension)



In-Cab Signalling Convergence

12

›CBTC, ETCS and PTC all have the same objectives:

›Continuous speed supervision – protection against derailments from excessive speed

›Protection against train to train and train to buffer stop collision

›Prevention of train movements through points in the wrong lie

›Protection of maintenance possessions from unauthorised train movements

So why can’t one solution meet all these requirements?



Signalling Control Trends

13

›It’s all about the money!

›Centralisation

›Train regulation

›Improved recovery from disturbances

›Quicker response and control in degraded modes

›Improved management emergency situations

›Possibility of backup control facilities and transfer of control

›Operational/passenger control – not just signalling control

Modernisation



4 Lines Modernisation - LU

16

›Automatic Train Control implementation on District, Metropolitan, Hammersmith &City and Circle lines for GoA2 operation

›Replaces tripcock train protection with 2 aspect colour light signals and distributed interlockings

›Centralises control in one location from 13 previous control points

›Required to achieve 32 Trains Per Hour in the central sections

›Contract awarded to Thales in August 2015

›Radio based Seltrac implementation (no loops)

›Axle counters used for secondary train detection



Jubilee Northern Upgrade Programme - LU

17

›Jubilee implemented in 2011

›Northern implemented in 2014

›Contracted by Tube Lines to Thales for Seltrac product

›Inductive loop (not radio communication)

›Jubilee currently being optimised to achieve closer to 36 TPH under Capacity Optimisation Programme

›Centralised control for each line in Operational Control Centres

›Axle counters used for secondary train detection



New Tube for London - LU

18

Planned upgrade of the Piccadilly, Central, Bakerloo and Waterloo & City Lines

RCS scope includes signalling, operational control and communications

Unmanned operation (GoA4) planned for 3 lines

Piccadilly Line planned for 36TPH

Estimated £1Bn upgrade for RCS alone

Due out to tender in 2016



Victoria Line Upgrade - LU

19

›Implemented in 2011

›Invensys (now Siemens) Distance to Go Radio product

›First GoA2 upgrade of a GoA2 line in the world

›Complex migration – dual fitted infrastructure to save on rolling stock fitment

›Under the LU Capacity Optimisation Programme, currently being optimised to closer to 36 TPH



Glasgow Subway Modernisation

20

›Currently in procurement with two suppliers shortlisted

›Thales/CAF consortium and Ansaldo STS/Stadler consortium

›Currently uses contactless trainstops for ATP

›Simple circle line layout with one depot access and minimal crossovers

›Planned for GoA4 operation – the first in the UK outside of airport people movers



Crossrail 1

21

›New cross London railway linking Great Western and Great Eastern Mainlines
