Side platform

Station with two tracks
and two side platforms

A side platform is a platform positioned to the side of a pair of tracks at a railway 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 to 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 running above and over 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.

Where the station is close to a level crossing (grade crossing) the platforms may either be on the same side of the crossing road or alternatively may be staggered in one of two ways. With the 'near-side platforms' configuration, each platform appears before the intersection and with 'far-side platforms' they are positioned after the intersection.

In some situations a single side platform can be served by multiple vehicles simultaneously with a scissors crossing provided to allow access mid-way along its length.

Most stations with two side platforms have an 'Up' platform which is used by trains heading towards the primary destination of the line, with the other platform being the 'Down' platform which takes trains heading the opposite way. Normally, the main facilities of the station are located on the 'Up' platform with the other platform accessed from a footbridge, subway or a track crossing. However, in many cases the station's main buildings are located on whichever side faces the town or village the station serves.

Larger stations may have two side platforms with several island platforms in between. Some are in a Spanish solution format, with two side platforms and an island platform in between, serving two tracks.
