DOLPB2 & DOLPB3.
• Saloon doors must not be opened when train is not at the
station & confirm the platform side before manually opening
doors.
• After stabling the train in depot the TO should ensure proper
locking of all doors before leaving the train and also after
completion of job card, doors locking should be ensured.
• Before opening emergency door, availability of adequate
space in front of train should be ensured.

Door System
Driving assembly consist of a driving screw ( spindle rod) and a ball-nut system.
The screw is right hand threaded over one half of its length and left hand threaded over the other
half.
Each half is assembled with a nut which is linked via fork to the corresponding door leaf.
Each nut is installed with a roller which travels along a groove in the main beam. This roller
prevents the nut from rotating during the translation phase and gets locked in the groove near
centre hook which prevents the un-intentional opening of the doors.

14. Door limit switches
• Two Door Lock Switches (DLS) which
check the door locked position and is
operated after the DCS operation i.e
first the doors are closed and then
locked.
• Two Door close switches (DCS) which
check the door close position.

15. • Push-back Device : After the doors are closed and locked, the re-opening
of each door leaf by 11 mm ± 5 mm (10 mm total gape). Push-back device
is incorporated in the linkage between the “driving nut” and driving arms,
so that a “locked” door panel is pushed-back.
• The push-back is a spring loaded device. The spring is compressed when
any attempt to open the doors manually is made and forces the door
leaves to return to their original position. After door is locked, the force to
reopen one door leaf is between 80 N and 120 N.
Note – operation of Push back device does not operate DCS.

23. Door lower guiding
The lower guiding prevents small objects to fall in the rail and block it.
The lower guiding of the door is a U-shape profile fixed on the car body shell.
A stainless steel sheet inserted inside the guiding rail allows an easy sliding of the door leaves.
Recessed pads are at the middle of the guiding rail in order to prevent the vibration of the door
leaves when door is closed and locked.
24. • At the center, the main beam groove (1) includes locking slots perpendicular to the drive screw (5)
and into which the rollers (2) (integral with the nuts), rotate when the door leaves have come to
the "door closed" position
Locking of the leaves is caused by the rotation of the nuts under the effect of:
The torque exerted by the electric motor on the screw in case of automatic closing.
Return spring (3) which drives each nut in case of manual closing.

25. • Types of door unlocking system:
• Automatic Unlocking
The automatic unlocking is achieved by rotation of the nut caused by the torque exerted by
the motor on the screw during automatic opening.
. Emergency Unlocking
• Release is achieved by a finger (1) articulated around the central bearing (2) of the screw and
nut system, which rotates the ball-nuts so that the guide rollers (4) are removed from the
locking slots.
