A train station, railway station or simply a station is a railway facility where trains regularly stop for passengers.

Generally, stations consist of one or more platforms providing easy access to board and alight arriving train services. Most urban stations have a variety of features such as ticket sales staff (or machines), travel card swipe devices, waiting rooms, toilets, CCTV, etc. Stations may be staffed full or part time and would usually have revenue protection officers or security officers randomly present.

Typically located close to intersections with major roads, stations may be at, below or elevated relative to surrounding ground level.

Within the centre of major cities, they are often in underground tunnels or upon viaducts (elevated tracks).

Access to other transport modes such as intersection rail lines (junction stations), buses, trams or light rail may be provided.

Some suburban stations may have all-day car parking and "kiss and go" drop-off points for car passengers.

A through station is a station along the line. A terminus is the station at the end of the line from which the train makes a return trip.
