A train station, also referred to as a railway station (in Commonwealth English) or a railroad station (in US English) and often shortened to just station, is a railway facility where trains regularly stop to load or unload passengers and/or freight. It generally consists of a platform next to the track and a station building (depot) providing related services such as ticket sales and waiting rooms. If a station is on a single track main line, it often has a passing loop to facilitate the traffic. The smallest stations are most often referred to as 'stops' or, in some parts of the world, as 'halts' (flag stops).

Stations may be at ground level, underground, or elevated. Connections may be available to intersecting rail lines or other transport modes such as buses, trams or other rapid transit systems.
