The Stour Valley Line is the present-day name given to the railway line between Birmingham and Wolverhampton, in England. It was authorised as the Birmingham, Wolverhampton and Stour Valley Railway in 1836; the title was often shortened to the Stour Valley Railway.
The line opened in 1852, and the line is now the main line between those places. Associated with its construction was the building of the major passenger station that was later named New Street station, and also lines in tunnel each side of the station, connecting to the existing routes. The station was opened in 1854.
Before completion, the Company became controlled by the London and North Western Railway, which used dubious methods to harm competitor railways that were to be dependent on its completion.
The line was electrified in 1966 and now forms part of the Rugby–Birmingham–Stafford line, an important and very heavily used part of the railway network.
