Platform Screen Doors

Platform screen doors enhance commuter safety by providing a barrier between the station platform and the track.

It prevents unauthorised entries onto the track, minimizing service disruption due to track intrusion. In addition, full-height platform screen doors act as an environmental screen to cut down air-conditioning energy by up to 50%.

All platform screen doors have an interlocking system with the signalling system to prevent the train from departing when any door is not closed and locked.

Each bi-parting door also has an emergency release mechanism to allow passengers on board the train to manually slide open the bi-parting doors in case of a system failure.

Newer platform screen doors have been designed with a modernised look, incorporating more glass surfaces and sporting an ergonomic design. They also produce less noise when the doors operate.

The newer platform screen door systems have green summary indicator lamps located at both ends of the platform, which illuminates when all doors are fully closed and locked.
