Gloucester railway station (formerly known as Gloucester Central station) is a railway station serving the city of Gloucester in England. The station was originally built as the terminus of the Birmingham and Gloucester Railway in 1840, but the arrival of the (broad gauge) Bristol and Gloucester Railway and Cheltenham and Great Western Union Railway in 1844, and then conversion to a through station for the South Wales Railway in 1851 resulted in a very complex layout. Subsequent closures and rationalization have left Gloucester with a station that is located off the main Bristol-Birmingham line, meaning trains that call at Gloucester usually have to reverse. Only trains that continue along the Gloucester to Newport Line do not have to reverse.
