Lighting columns

3.5.1 The requirements for the position of lighting columns on platforms is set out

in GI/RT7016

and GC/RT5212. GE/RT8000 sets out requirements for maintenance of lighting

columns

and luminaires (see G 3.5.1.8). There are no railway specific requirements for

the design and manufacture of lighting columns.

Section Name

Lighting Column SpecificationG 3.5.1.1

For the design of lighting columns, the following aspects should be considered:

a) Geometric limits on the location and height of columns.

b) The relevant design loading (for example, wind and vehicular impact).

c) The ground conditions and their influence on the type and method of fixing and

maintaining the column in position.

d) The durability requirements for the lighting columns (for example, risk of

corrosion).

e) The space required for lowering the head frame or the whole column, in the

case of raising and lowering columns, without requiring a track possession or

isolation of the overhead line equipment.

f) The means of safe access for lamp maintenance without disturbing the

operational railway.

g) The vulnerability of the lighting columns and luminaires to attack from vandals.

Section Name

Lighting Column SpecificationG 3.5.1.2

Lighting columns are generally designed in accordance with the definitions

and terms of BS EN 40-1:1992 and the general requirements and

dimensions of BS EN 40-2:2004 respectively, for the material selected (for

example, steel, aluminium or concrete). The document PD6547 gives

guidance on the use of BS EN 40-3-1:2000 and BS EN 40-3-3:2003.

The flexural test rig is design to replicate the following forces using

incremented weight loading:

1. Lantern weight and windage.

2. Additional attachments such as signs.

3. County wind velocity.

4. Wind pressures associated with county altitude.

5. Torsional forces associated with outreaches & offsets.

Basic Overview of Test

Column specified for use is loaded with dead loads which simulate known

forces at critical points along the columns length.

Dead loads are applied in five equal increments up to the minimum

ultimate test load i.e. if load is 50kg weight is added in 10kg increments

Column should return to its natural state once dead loads have been

removed to pass test.

Marking for lighting columns

As of July 1st 2013 “The CE Marking is mandatory and must be

affixed before any product is placed on the market and put into service.”

This is a legal requirement
