Introduction
This document specifies the minimum requirements for construction and operation of railway
passenger access systems to ensure:
— safe access and egress from passenger trains through body side doors and steps;
— usability for persons with reduced mobility;
— a minimum risk of injury to persons as a result of door and step operation;
— that the doors and moveable steps, ramps, bridging plates remain closed when the vehicle is in
motion; and
— safe maintenance of the entrance systems.
1 Scope
This document applies to passenger body side entrance systems of all newly designed railway vehicles
such as tram, metro, suburban, mainline and high-speed trains that carry passengers. The requirements
of this document also apply to existing vehicles undergoing refurbishment of the door equipment, as far
as it is reasonably practicable.
This document also specifies the requirements for testing of entrance systems.
This document makes reference to manual and power operated entrance systems. For manual doors,
clauses referring to power operation are not applicable.
This document does not apply to the following:
— entrance systems for equipment access, inspection or maintenance purposes and for crew only use;
— doors on freight wagons; and
— doors or hatches specifically provided for escape under emergency conditions.

4 Constructional requirements
4.1 Door design
4.1.1 Door throughway design
4.1.1.1 Minimum width
Doors shall have an unrestricted clear usable width (1) of 800 mm minimum to allow unimpeded access
and egress of passengers (Figure 1 shows two examples of doors). On trains where there is no step
between the threshold of a dedicated wheelchair access door and the adjacent vestibule, usable without
manual or semi-automatic ramps as defined in 4.11, that door shall have a minimum clear useable
width of 1 000 mm when open.
Key

2 door leaf 4 leading edge

4.1.1.2 Minimum height
Doors shall have an unrestricted vertical clearway height of l ≥ 1 900 mm minimum (see Figure 2 for
the measuring method).
Dimensions in millimetres
Key
l1 ≥ 1 900 mm
Figure 2 — Minimum height
4.1.2 Steps
4.1.2.1 Entrance area − General
External steps shall have at least the same clear width as the door and be in line with the throughway of
the door.
Internal steps should have at least the same clear width as the door and be in line with the throughway
of the door.
Passenger access from the defined platform to the vestibule of the vehicle shall be achieved with a
maximum of four steps.
4.1.2.2 Step dimensions
4.1.2.2.1 Internal steps for external access
Internal steps for external access shall have a maximum height of l = 200 mm and a minimum depth of
l = 240 mm between the vertical edges of the step. The rising height of each step shall be equal.
The height of each step may be increased to a maximum of l = 230 mm if it can be demonstrated that
this achieves a reduction of one in the total number of steps required.
EXAMPLE If a vertical distance of 460 mm is to be traversed, it can be demonstrated that using steps of up to
l1 = 230 mm reduces the number of steps required from 3 to 2.
See Figure 3 for details.
4.1.2.2.2 External steps
An external access step, fixed or moveable, shall have a maximum height of l = 230 mm between steps
and a minimum depth of l = 150 mm.
Dimensions in millimetres
Key
1 fixed steps inside the train l ≤ 200 or ≤ 230 l ≥ 240
1 4
2 external fixed or moveable step l2 ≤ 230 α ≤ 59°
3 door leaf l3 ≥ 150 β ≤ 55°
Figure 3 — Step dimensions
A minimal drop in level, with a maximum of l = 60 mm (Figure 3), between the floor surface of the
vestibule/last step and that of the external step of the vehicle used to guide and seal the door is also
permissible and shall not be considered as a step so the minimum depth of l = 150 mm (Figure 3) does
not apply. See Figure 4 for the permissible position of the external extension of the door sill.
If the external step depth l is ≥ 150 mm the surface of the exterior step may be used as a reference for
defining the stepping height when stepping up from a lower platform whereas the floor surface of the
vestibule may be used when stepping down from a higher platform.
If a step is fitted and it is an extension of a door sill outside the vehicle, and there is no drop in level
between the floor surface of the vestibule and that of the external step of the vehicle, this shall not be
considered to be a step for the purposes of this specification. See Figure 4 for details.
Key
1 floor surface vestibule l1 ≤ 60 mm
2 extension of door sill

4.1.2.3 Step surface
Steps shall be provided with a slip resistant surface across the usable surface area.
The first and the last step inside the vehicle shall be indicated by a contrasting band with a depth of
45 mm to 55 mm extending the maximum useable width of the steps on the front and the top surfaces
of the step nosing.
The first and the last step outside the vehicle shall be indicated by a contrasting band with a depth of
45 mm to 55 mm extending the full width of the steps on the top surfaces of the step nosing.
4.1.2.4 Protection against water accumulation
The steps shall be arranged to allow water to drain away from the anti-slip surface. The design shall
prevent water accumulation.
4.1.2.5 Manual operation
If a retractable step fails to close and the deployed step exceeds the vehicle kinematic gauge, it shall be
possible to manually retract the step to a closed position, particularly from the platform it is intended
for.
The operation manuals shall include an instruction stating that the step drive shall be isolated prior to
manual operation, if this is necessary to avoid a possible injury due to the activation of the automatic
drive.
4.1.3 Track level access
If required in the technical specification, means shall be provided to ensure access and egress to and
from the track level for staff on dedicated doors. Details need to be clarified in the technical
specification as far as not defined in EN 16116-1.
4.1.4 Relative position of the step edge
The relative position of the step edge in relation to the vehicle body shell and vehicle floor (dimensions
l and l of Figure 3) shall be defined in the technical specification considering the requirements
2 3
regarding the gap between step and platform.
NOTE See EN 16586-1:2017 for further details.
4.1.5 Train surfing
Handholds on the outside surface of the entrance system shall be avoided or designed so they are
minimizing grip when the doors are closed (to avoid so called 'train surfing') unless needed for crew
access.
4.1.6 Door windows
Doors shall be fitted with transparent windows to allow passengers to identify the presence of a
platform.
All door windows shall be fitted with safety glass (either laminated or toughened glass) which is in
accordance with a relevant national or international standard. Other material achieving a comparable
level of safety may also be used.
Where the distance of the lower edge of the door window is less than h 800 mm (recommended
1 =
1 000 mm) above vehicle floor level adjacent to the door, a means of protection shall be provided to
prevent passengers falling through the window when broken. Where internal steps are fitted this
dimension shall be increased to h 1 000 mm (recommended 1 200 mm).
2 =
In case there is a step downwards inside adjacent to the door the minimum dimension of h = 800 mm
(recommended 1 000 mm) shall be achieved (see Figure 5).
Protection may be achieved by the use of a suitable laminated glazing system retained by appropriate
fixing (mechanical retention, suitable bonding, etc.), or mechanical elements (e.g. a bar) or equivalent
measures. If bars are used, they shall be fitted so that they do not create hazards to passengers.

4.1.7 Design of body side entrance doors used for accessing driver's cabs
If a body side entrance door is used for accessing the driver's cab, the requirements shall be defined in
the technical specification.
4.1.8 Water drainage
Means shall be provided to divert water from the vehicle roof away from the door throughway.
