FAQs

Why do trains sometimes fail to stop at the correct position to the waiting lines, what are the procedures of High Capacity Systems for overshooting trains?

During normal operation, the trains’ signaling computers control acceleration, deceleration, and stopping according to the speed codes received from the wayside. Occasionally, weather conditions, such as rain, may cause the trains to stop at inaccurate positions. This is why our system allows for a ±30cm leeway at either side of the berthing position. Under normal circumstances, trains should berth accurately at the platform marks to let passengers on and off the trains.
Procedures in case of train overshooting are as follow:
1. If a train overshoots but no door misses the platform:
Driver informs OCC, then reverses to berth at the correct position before letting passengers on and off.
2. If a train overshoots and one door misses the platform:
Driver informs the OCC, then reverses the train to berth at the correct position to let passengers on and off. Alternatively, the driver may broadcast to inform the passengers that the doors will not open at the current station, and that passengers for this station need to take a returning train at the next stop, then proceed to the next stop to let passengers off.
3. When a train overshoots and two or more doors miss the platform:
(1) Driver informs the OCC and broadcasts to inform the passengers that the doors will not open at the current station, and that passengers for this station need to take a returning train at the next stop, then proceed to the next station to let passengers off.
(2) If overshooting occurs at a terminal or turn-around station, or in a last train, the OCC will instruct the driver to reverse to the correct berthing position.
