Railroad stations

A train station, railroad station, or railway station is a railway facility where trains stop to load or unload passengers, freight, or both. It generally consists of at least one platform, one track, and a station building providing such ancillary services as ticket sales, waiting rooms, and baggage/freight service. Stations on a single-track line often have a passing loop to accommodate trains traveling in the opposite direction. Locations at which passengers only occasionally board or leave a train, sometimes consisting of a short platform and a waiting area but sometimes indicated by no more than a sign, are variously referred to as "stops", "flag stops", "halts", or "provisional stopping places". The stations themselves 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.
