4 Requirements for lighting in passenger areas
4.1 General lighting
4.1.1 General

The quality of lighting influences visual performance, performance attitude, safety at work and general

well-being.

The lighting for rolling stock in heavy rail systems shall enable a range of visual tasks to be performed.

The requirements to be met by the lighting system are based on the following criteria:

— illuminance;
— uniformity;
— limitation of glare;
— colour temperature and colour rendering.
General lighting shall achieve the values set out in Table 1 or Table 2.

Where agreed between contractors, it is permissible for the general lighting system to adapt to the

ambient lighting, provided that the contribution from the general lighting system plus that from the

ambient lighting achieves the values set out in Table 1 or Table 2.
General lighting shall be provided in normal operation without interruption.

For high speed and long distance units, in the event of loss of the main power supply, general lighting

shall be provided for a period of not less than 10 min.

A lighting system can only satisfy specified requirements if all criteria mentioned above have been

taken into account. Depending on the type and level of the difficulty of the visual task, orientation of

seating, or of the type of accommodation to be lit, priority may be given to one or more of these criteria.

4.1.2 Illuminance and uniformity

Different requirements are made concerning the general lighting for rolling stock in heavy rail systems

according to the service and/or location. Two classes of vehicles are defined: (a) high speed and long

distance units and (b) other units.

a) For high speed and long distance units, the minimum value of the average illuminance and

uniformity requirements shall be in accordance with Table 1.

b) For other units, the minimum value of the average illuminance and uniformity requirements shall

be in accordance with Table 2.

c) By agreement between contractors, the requirements for high speed and long distance units may be

applied to other units.
This concept is taken from Commission Regulation 1302/2014 Clause 4.2.2.10 (2)

This is defined locally within specific areas of the vehicle, for example seating area

between doors to be evaluated separately from that between the doors and car-end.

Where the average illuminance is greater than 220 lx, the uniformity range 0,7 to 1,5 shall

apply.

In the case of seating areas in dining vehicles, the uniformity requirements shall not apply

and alternative illuminance levels may be agreed between contractors.
With additional but switched-off lighting at the vehicle access step.

Measured at 3 locations to be agreed between contractors, across the central 80 % of the

width of the vehicle access step, according to Annex B (normative).

width of the vehicle access step, according to Annex B (normative).
If a toilet is included, then the requirements of Table 1 ‘Toilets’ shall apply.

The values of illuminance given in this clause shall be achieved in the different locations in accordance

with the measuring points in 6.5.
4.1.3 Glare limitation

The lighting system shall be designed to minimize glare and to avoid glare from night time reflections in

windows. The glare rating for the lighting system, when calculated using the Unified Glare Rating (UGR)

tabular method set out in ISO 8995-1 shall be not greater than 22.
4.1.4 Correlated colour temperature

The correlated colour temperature of the lamps used for general lighting shall be between 2 800 K and

7 000 K.

NOTE 1 For reasons of visual comfort, colour temperatures above 5 000 K are not advisable.

For lighting system with fixed colour temperature characteristics, the range of correlated colour

temperatures for the lamps in a given part of a unit shall be not greater than 3 SDCM.

NOTE 2 The given part of a unit may be one vehicle of that unit.

In the case of lighting systems with adjustable colour temperature characteristics, the above SDCM

requirement shall apply to the nominal CCT value for all parts of the system.

NOTE 3 An example of an adjustable colour temperature system is a system with lower and upper CCT limits of

3 000 and 5 000 K, achieved by the mixing of two different types of ‘white’ LED.

continue to operate after being subjected to two successive test pulses in accordance with Annex C,

when mounted in a manner representative of its installation in a vehicle. Reduced visibility due to

airborne particles, caused by smoke or dust, should be taken into account in the design of emergency

lighting.

The emergency lighting shall be arranged to ensure that it will be switched on automatically and cannot

be made ineffective by passengers.
4.3.2 Power supply

The luminaires of the emergency lighting system shall be supplied from the energy storage system by at

least one power supply line which is independent from the general lighting system, such that the

emergency lighting remains operational in the event of the failure of the general lighting power supply

line.

NOTE 1 This ensures that the emergency lighting system remains operational in the event of failure of the

general lighting system supply.

NOTE 2 The normal arrangement is one common energy storage system and at least one separate power

supply line for the emergency lighting. Each power supply line has its own circuit breaker arrangement.

The power supply shall be designed so that in the event of a fire, a minimum of 50 % of the emergency

lighting in the vehicles not affected by fire shall be maintained for a period of time not less than 20 min,

or a period of time greater than 20 min by agreement between contractors.
4.3.3 Illuminance

The minimum value of the average emergency illuminance shall be 5 lx at floor level along the centre

line of the escape route.

The minimum value at the vehicle access step shall be 40 lx (when body side door is open).

Safety signs may be made of photoluminescent material conforming to the requirements of DIN 67510

or an equivalent publicly available standard. Where photoluminescent signs are used, the minimum

value of illuminance over the surface of the exit signage shall be 50 lx under general lighting.

NOTE This ensures the correct functioning of photoluminescent materials.
All values shall be measured in accordance with 6.4, 6.5 and 6.6.
4.3.4 Uniformity of illuminance

The uniformity ratio of the emergency lighting, measured along the centre line of the escape route in

accordance with 6.4, 6.5 and 6.6 shall be between 0,15 and 5,0.
4.3.5 Glare limitation

In order to minimize glare effects, the luminance of the emergency luminaires shall not exceed

400 cd/m in the usually visible surface (between 0° and 60° below the horizontal plane of the

luminaire).
4.3.6 Starting performance

The minimum starting performance of the emergency lighting is such that 50 % of the fully specified

illuminance shall be achieved within 5 s, and the fully specified illuminance within 15 s.

4.3.7 Operating time
The operating time of the emergency lighting shall be ensured for
— high speed and long distance units: at least 3,0 h;
— other units: at least 1,5 h
after the power supply, e.g. the battery charging system, has failed.

The specified times applicable to a fully charged energy storage system under specified conditions shall

be agreed between contractors. Also, by agreement betw
