The South Staffordshire line is a partially mothballed and active former mainline that connects Burton-upon-Trent to Lichfield in Staffordshire and formerly then to the West Midlands towns of Walsall, Wednesbury, Dudley and Stourbridge. However, Dudley and Stourbridge were already joined to the Oxford, Worcester and Wolverhampton Railway's (OW&WR) line just north of Dudley Station. It in essence, continued to Stourbridge (Dudley and Stourbridge were later to become part of the West Midlands conurbation) along with Wednesbury and Walsall.
