A side platform is a platform positioned to the side of one railway tracks
or guideways at a rail station, tram stop, or transitway. Dual side platform
stations, one for each direction of travel, is the basic station design used
for double-track railway lines (as opposed to, for instance, the island
platform where a single platform lies between the tracks).
Side platforms may result in a wider overall footprint for the station compared with an island platform where a single width of platform can be shared by riders using either track.
In some stations, the two side platforms are connected by a footbridge above or underpass the tracks. While a pair of side platforms is often provided on a dual-track line, a single side platform is usually sufficient for a single-track line.
Most of elevated MRT and LRT stations in Kuala Lumpur are designed with side platform architecture.
