When applying colour to two adjacent surfaces, to provide sufficient contrast, the contrast between the colours
will be determined by the light reflectance value, the hue and by the chromatic value of each. (D)
For the purposes of this Standard “Contrast” shall be assessed by the diffused light reflectance value, but may
be enhanced by variation in hue and chroma. For Testing methods see EN for PRM.
3.22
tactile signs and controls
―Tactile signs and ―tactile controls are signs or controls, including raised pictograms, raised characters
or Braille lettering. For tactile pictograms and characters the depth shall be a minimum of 0,5mm raised above
the surface and shall not be engraved and shall be square edged (i.e. not rounded or sharp).
The character or pictogram spacing should allow for both sides of the embossed letter, number or symbol to
be felt with the fingers in a single pass.
The minimum character or number height shall be 15mm.

4.1.2 Steps
4.1.2.1 Entrance area −−−− General
External steps shall have at least the full door width and shall be in line with the door throughway.
Internal steps should have at least the full door width and should be in line with the door throughway.
Access to the vestibule of the vehicle shall be achieved with a maximum of 4 steps of which one may be
external.
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 (going) 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.
(For example, if a vertical distance of 460 mm is to be traversed, it can be demonstrated that using steps of up
to l =230 mm reduces the number of steps required from 3 to 2.)
Details see Fig 3
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. If a step is fitted and it is an extension of a door sill outside the vehicle, and
there is no change in level between the step and the floor of the vehicle, this shall not be considered to be a
step for the purposes of this specification. Details see Fig 3

A minimal drop in level, with a maximum of l =60 mm, between the floor surface of the vestibule 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 doesn’t apply. See Figure 4 the permissible position
of the external extension of the door sill.
In case 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 vehicle floor surface may be
used when stepping down from a higher platform.

water accumulation.
4.1.2.5 Manual operation
If the deployed step exceeds the vehicle gauge, under power failure conditions the step shall be manually
retractable to a stable closed position from the platform it was intended for.
The operation manuals shall include an instruction stating 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.
It shall be possible to operate the step manually in case of power failure. Under this condition a means of
ensuring the stability of the open position and a facility for manual retraction shall be provided.
4.1.3 Track level access

be defined in the contract considering the requirements regarding the gap between step and platform.
4.1.5 Train surfing
Step edges, ledges or handholds on the outside surface of the door system shall be avoided or designed so
they are not accessible, when the doors are closed (to avoid so called “train surfing“).
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.
Where the distance of the lower edge of the door window is less than 800 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. In case of internal steps this dimension shall be increased to 1000 mm.
NOTE Protection may be achieved by the use of a suitable laminated glazing system retained by appropriate fixing
(mechanical retention, suitable bonding etc), mechanical elements (eg. a bar) or equivalent measures. If bars are used,
they should be fitted such that they do not create hazards to passengers.
4.1.7 Design of Entrance doors to drivers cabs
Further detrails are defined in prEN16186-1
4.1.8 Water drainage
A system shall be provided to divert water from the vehicle roof away from the door throughway.
4.2 Mechanical strength
4.2.1 Door mechanical strength
4.2.1.1 Passenger retention
The door system shall be capable of withstanding the forces that occur when passengers are leaning or falling
against the door panels without causing any non-elastic deformation or loss of operation (service force is
repetitive). Deformation on first loading shall not be considered during testing.
For this purpose a closed and locked door panel including the glazing shall withstand a pushing force applied
from inside the vehicle onto the door panel.
The load shall be represented by the application of a load distributed over a strip of 200 mm in height,
positioned l =1300 mm above car floor level. The value of this force shall be 1000 N per linear metre over the
width of the exposed internal surface of the door (see also Figure 5).

4.2.1.2 Aerodynamic stresses
A door system shall be capable of withstanding the effects of pressure pulses as given in Annex F, applied
over the surface of the door without causing any non-elastic deformation or loss of operation. Deformation on
first loading shall not be considered during testing.
4.2.1.3 Vehicle gauge
Under normal operation the loads defined in 4.2.1.1 and 4.2.1.2 may cause elastic door deformations. The car
builder shall specify the acceptable limits so as not to infringe the kinematic gauge of the vehicle in the
contract.
4.2.1.4 Vehicle overturning case
It shall be specified in the contract if the door strength is to be based on the vehicle overturning case.
During the vehicle overturning case, the door shall not break away. This is based on the passengers of a
crush laden train standing on the door (6 kN/m²). Non-elastic deformation is permissible.
NOTE EN 15663 provides typical passenger weight and occupation.
4.2.1.5 Ability to withstand vibration and shock
The door system shall be designed to withstand the effects of vibrations and shocks as defined for equipment
attachments in EN 12663-1.
If vibration and shock testing of sensitive mechanical components is specified in the contract, this shall be
carried out in accordance with EN 61373.
4.2.2 Step(s) mechanical strength
The following requirements shall apply:
 the steps shall be capable of withstanding a concentrated downward vertical load of 2 kN. This shall be
applied on an surface area of 100 mm × 200 mm at any position on the exposed step surface without
causing non-elastic deformation;
 the steps shall be capable of withstanding on their exposed surface a distributed downward vertical load
of 4 kN/m of step length without causing non-elastic deformation (see Figure 6);
