Also Known As Platform screen doors (PSDs), & Platform edge doors (PEDs), are used at some [[train station|train]], rapid transit and people mover stations to separate the platform from train tracks, as well as on some [[bus]] rapid transit, tram and light rail systems. Primarily used for passenger safety, they are a relatively new addition to many metro systems around the world, some having been retrofitted to established systems. They are widely used in newer Asian and European metro systems, and Latin American bus rapid transit systems.
