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

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

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.

4.1.5 Colour rendering
The ability of a light source to render colours of surfaces accurately is important for safety and comfort.
The Colour Rendering Index R of the light sources as defined in IEC 60050-845:1987/AMD1:2016, shall
a
be ≥ 80 or colour rendering group 1B.
4.1.6 Illuminance in vehicles for night service
In vehicles that are intended predominantly for night service, the lighting shall be arranged to meet
particular requirements concerning minimum illuminance.
— In passenger seating areas, the emergency lighting illuminance requirements of 4.3.3 shall apply.
— In sleeping compartments, individual subdued sleeping lighting should be provided. Where
provided, general light switches shall be internally lit.
4.1.7 Reduced lighting
For energy conservation or for passenger comfort, a proportion of the general lighting may be switched
off or be reduced (for example by dimming the whole or parts of the system) in passenger seating areas.
Where provided, the requirements for reduced lighting shall be as follows:
The minimum lighting requirement shall be the emergency lighting illuminance requirements of 4.3.3.
In passenger access areas (e.g. vestibules, stairways, corridors) the illuminance and uniformity shall be
in accordance with Table 1 or Table 2, as applicable. Where provided for passenger use, general light
switches shall be internally lit.
4.1.8 Lighting control functions
For special tasks, e.g. cleaning and lamp testing, it is recommended that a dedicated switching device is
provided at a place in the vehicle that is convenient to the service people.
4.1.9 Photobiological safety
Lighting systems shall comply with the requirements of EN 62031:2008, Clause 22.
The blue light hazard shall be not higher than risk group 1 (Low-Risk) as defined in EN 62471:2008.
4.2 Stand-by lighting
Stand-by lighting is not mandatory. However, where provided, the duration of stand-by lighting shall be
agreed between contractors. Unless otherwise agreed between contractors, stand-by lighting
illuminance shall be a minimum of 30 % of the general lighting illuminance.
4.3 Emergency lighting
4.3.1 General
Emergency lighting shall be provided to operate in the event of the switching off or failure of general or
stand-by lighting. Luminaires of the general lighting system may be used for the emergency lighting
system.
The emergency lighting shall be designed to enable continued occupation or safe egress from the
vehicle, including the exit route. The emergency lighting shall be designed to illuminate the exit signs
and the associated equipment.
The emergency lighting system shall provide the light necessary to enable passengers to move inside
vehicles and leave vehicles and in particular to recognize the presence of obstacles.
13
---------------------- Page: 15 ----------------------
SIST EN 13272-1:2020
EN 13272-1:2019 (E)
Where required according to agreement between contractors, the emergency lighting system shall
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
2
400 cd/m in the usually visible surface (between 0° and 60° below the horizontal plane of the
