The
Western Region was a region of
British Railways from 1948. The region ceased to be an operating unit in its own right in the 1980s and was wound up at the end of 1992. The Region consisted principally of ex-
Great Western Railway lines, minus certain lines west of
Birmingham, which were transferred to the
London Midland Region in 1963 and with the addition of all former
Southern Railway routes west of Exeter, which were subsequently rationalised.
