11.2.2. Doors

Doors leading into tramcars with designated seats or designated wheelchair space(s)
shall have an obstacle-free width of one single door of 900 mm. If a double door is
used, the obstacle free width of each door shall be 900 mm. The width may be reduced
by 100mm when measured between handholds.

All doors shall be automatic. When a door is opening or closing, there shall be an
acoustic and visual warning signal to alert/inform passengers.

When the car door is enabled for opening, a signal shall be given that is clearly visible
and audible to persons inside and outside the train. This acoustic alert signal shall
sound for a minimum of 5 seconds. This visual alert signal, e.g. a red light, shall flash
during the same period. When a door is automatically or remotely opened by the driver
or member of the train crew, the acoustic alert signal shall sound for a minimum 3
seconds from the moment that the door starts to open. This visual alert signal shall flash
during the same period.

When a door is automatically or remotely closed, or about to operate, a signal shall be
given to passengers inside and outside the train. The acoustic alert signal shall sound
for a minimum of 2 seconds before the door starts to close and shall be different in tone
to that used when the door is opened. This visual alert signal shall flash during the
same period. The signal shall continue while the door is closing.

The door, once opened, shall remain open for a period of not less than 5 seconds
before it closes.

Automatic doors shall incorporate devices that detect if any door is about to close on a
passenger. When a passenger is detected, the doors shall stop automatically and
remain open for a limited period of time. Sensors at two heights shall be provided to
avoid doors trapping persons using mobility devices or guide dogs.

Doors shall be color contrasted, at least LRV 30, in order to be easy to locate from the
inside and outside of the vehicle.
