FAQs

Why does the train sometimes fail to stop in the correct position for waiting lines, and what is the procedure of High Capacity System for train overrun?

The signal computer controls the train's acceleration, deceleration and train stop in normal operation. The weather factor (ex: a rainy day) may prevent the train from stopping in an accurate position, hence our systems design an allowed error of on either side 30 cm. Under normal conditions, the train should stop in the accurate position.
If a train overshoots , the procedure is as follow:
1. If a train overshoots but no door exceeds the platform:
(1) In a station without platform doors, the driver will open car doors manually to allow passengers to disembark.
(2) In a station with platform doors, the driver will reverse the train and berth in the correct position before allowing passengers to disembark.
2. If a train overshoots and one door exceeds the platform:
(1) In a station without platform doors, the driver will isolate and lock the door in the overshoot section, and instruct passengers to disembark from other doors, but if the car is too crowded, the driver will inform OCC.
An announcement will be made informing passengers that the car doors will not be opened at this station and that passengers who wish to disembark will have to do so at the next station. (Passengers will then have to take the returning service back to their destination station.) The train will then move forward slowly to the next station for passengers to disembark.
(2) In a station with platform doors, the driver will either reverse the train and berth in the correct position before allowing passengers to disembark, or the driver will inform OCC. An announcement will be made informing
passengers that the car doors will not be opened at this station and that passengers who wish to disembark
will have to do so at the next station. (Passengers will then have to take the returning service back to
their destination station.) The train will then move forward slowly to the next station for passengers to disembark.
3. If a train overshoots and two or more doors exceed the platform:
(1) The driver will inform OCC. An announcement will be made informing passengers that the car doors will not be opened at this station and that passengers who wish to disembark will have to do so at the next station.
(Passengers will then have to take the returning service back to their destination station.)
The train will then move forward slowly to the next station for passengers to disembark.
(2) If overshoot occurs at a terminal or turn-back station, or is the last train service, OCC will instruct the driver to reverse the train to the correct berthing position.
(3) If the overshoot occurs during a late night service, the overshoot will be treated on a case by case basis.
Based on customer service and operational safety considerations, OCC will instruct the driver to either isolate the doors, reverse to correct berthing position, or go to the cab at the other end of the train and drive the train to the correct berthing position.
