Automatic platform screen doors, also known as platform edge doors, are safety installations at metro or subway stations which consists of floor-to-ceiling type sliding doors or half-height doors that isolate the platforms from the train track area. The key purpose of these doors is to prevent passengers from accidentally falling onto the tracks or being hit by trains pulling into and out of stations. APSD help address safety issues and also improve operational efficiency of metro rail systems.

Safety Benefits of APSD

One of the major reasons for installing Automatic Platform Screen Doors is to improve passenger safety. These doors eliminate the possibility of anyone falling or slipping onto the train tracks from the platform edges. According to statistics, a significant number of passenger deaths or injuries occur due to accidental falls onto train tracks every year across various metro networks. The installation of platform screen doors at station platforms prevents such mishaps and makes the system much safer for commuters.

Automatic platform screen doors also help address security issues to some extent. They prevent unauthorized access to tracks which can potentially delay train services. These smart doors are shut tightly whenever a train is entering or exiting a platform, thus ensuring no passengers linger too close to the tracks. This enhances safety while reducing risks of untoward incidents like passenger collisions with trains.

Operational Efficiency Gains

Apart from safety benefits, APSD also help improve operational efficiency of metro rail networks. With these doors sealing off platforms, train dispatch can be precisely synchronized. They allow faster and safer train movements into and out of stations as drivers don't need to slow down or stop abruptly at platform edges.
