Platform screen doors are safety systems that protect transit passengers and keep stations comfortable.
As metro, light rail, and urban rail become the primary mode of transport in major cities worldwide, platform screen doors (PSD) are being installed more widely to prevent accidental falls onto the tracks and improve the passenger experience. A PSD is an automatic door system that separates the platform from the track and opens and closes in sync with train doors. It keeps people and objects from falling onto the tracks, shields the platform from dust, noise, and fire, and provides a safer, more comfortable station environment.
Installation Benefits
-
01Passenger Safety
Prevents accidental or intentional falls onto the tracks, blocks heat and smoke in a fire, and provides a safe evacuation route in emergencies
-
02Comfort & Environment
Blocks train wind (piston effect), noise, and dust to improve the platform environment
-
03Passenger Flow
Creates a defined, orderly space connecting passengers and trains
-
04Energy Savings
Separates the air-conditioned platform from the track in remodeled stations, reducing energy use
-
05Profitability
Generates advertising revenue on PSD wall surfaces
