Platform Screen Doors (PSD)
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.

Full Height Platform Screen Doors (FHPSD) - 1st Generation
There are generally 2 series of the full height platform screen doors in use. The first series, installed at the North South & East West Lines stations, opened in 1987.

The network features 34 underground platforms and a total of 816 doorways; each platform has 24 sets of bi-parting doors aligned with the 6 car 4-door trains.

The pneumatically operated system has an outstanding reliability record achieving 99.99% average availability.
