Cambrian Railways owned of track over a large area of mid-Wales. The system was an amalgamation of a number of railways that were incorporated in 1864, 1865 and 1904. The Cambrian connected with two of the larger railways to give connections to the North West of England, via the London and North Western Railway; and with the Great Western Railway for connections between London and North Wales. The Cambrian Railways were absorbed by the Great Western Railway on 1 January 1922 as a result of the Railways Act 1921. The name is continued today in the route known as the Cambrian Line.
