High Quality Content by WIKIPEDIA articles! An island platform (also known as center platform or centre platform) on a railway is where a single platform lies between at least two tracks, serving both of them. Usually, the two tracks are on the same line, running in opposite directions. One station may have two island platforms in a four-track express configuration; in this case each platform may serve trains in one direction, with local and express trains stopping on opposite sides of a single platform. Island platforms generally have a lower construction cost and require less space than side platforms, a pair of separate platforms with the tracks running between them. However, island platforms may become overcrowded, especially at busy stations, and this can lead to safety issues such as Clapham Common (see image) and Angel (now rebuilt) on the London Underground, or else the curves at either end of an Island platform can impose undesirable speed limits, such as at Belmore, Turrumurra and in Melbourne.
