| Platform Screen Doors - Introduction |
Platform screen doors by Westinghouse Brake and Signal Company Ltd are installed at all underground MRT stations. It was the first heavy rail system in the world to incorporate platform screen doors in its stations in 1987.
They are used for the first time at underground stations anywhere in the world to cut down air-conditioning energy by up to 50%. The doors which are expected to be operated more than 300 times daily also hold back the uncomfortable blast of air from an approaching train.
The latest series of platform screen doors sporting a sleeker design, producing less sound when the doors were opened and closed, and incorporating more glass were installed.

A typical peak period scenario in an MRT station includes heavy boarding and alighting activities, crowded trains despite decent frequencies, especially in interchange stations. Travel time is also usually longer than the what signboards in platforms stipulate given the huge crowd and other factors like train bunching.
