Railway platform
A railway platform is an area in a train station alongside a railway track providing convenient access to trains. Almost all stations have some form of platform, with larger stations having multiple platforms.
Grand Central Terminal in Midtown Manhattan hosts 44 platforms, more than any other rail station in the world. The world's longest station platform is at Hubballi Junction in India at 1,507 metres (4,944 ft). The Appalachian Trail station or Benson station in the United States, at the other extreme, has a platform which is only long enough for a single bench.
Among some American train conductors, the word "platform" has entered usage as a verb meaning "to berth at a station", as in the announcement: "The last two cars of this train will not platform at East Rockaway".
The most basic form of platform consists of an area at the same level as the track, usually resulting in a fairly large height difference between the platform and the train floor. This would often not be considered a true platform. The more traditional platform is elevated relative to the track but often lower than the train floor, although ideally they should be at the same level. Occasionally the platform is higher than the train floor, where a train with a low floor serves a station built for trains with a high floor, for example at the Dutch stations of the DB Regionalbahn Westfalen (see Enschede). On the London Underground some stations are served by both District line and Piccadilly line trains, and the Piccadilly trains have lower floors.
A tram stop is often in the middle of the street; usually it has as a platform a refuge area of a similar height to that of the sidewalk, e.g. 100 mm (4 in), and sometimes has no platform. The latter requires extra care by passengers and other traffic to avoid accidents. Both types of tram stops can be seen in the tram networks of Melbourne and Toronto. Sometimes a tram stop is served by ordinary trams with rather low floors and metro-like light rail vehicles with higher floors, and the tram stop has a dual-height platform. A railway station may be served by heavy-rail and light-rail vehicles with lower floors and have a dual- height platform, as on the RijnGouweLijn in the Netherlands.
In all cases the platform must accommodate the loading gauge and conform to the structure gauge of the system.
Platform types include the bay platform, side platform (also called through platform), split platform and island platform. A bay platform is one at which the track terminates, i.e. a dead-end or siding. Trains serving a bay platform must reverse in or out. A side platform is the more usual type, alongside tracks where the train arrives from one end and leaves towards the other. An island platform has through platforms on both sides; it may be indented on one or both ends, with bay platforms. To reach an island platform there may be a bridge, a tunnel, or a level crossing. A variant on the side platform is the spanish solution which has platforms on both sides of a single through track.
Modern station platforms can be constructed from a variety of materials such as glass-reinforced polymer, pre-cast concrete or expanded polystrene, depending on the underlying substructure.
