The GJR amalgamated with other railways to form the London and North Western Railway (LNWR) in 1846. The present line was completed in 1881, when the LNWR constructed two spurs from the GJR at Wolverhampton and Walsall. The Wolverhampton spur diverged south from the original line and linked to Wolverhampton (High Level) station. The spur at the Walsall end diverged north from the GJR and linked to the South Staffordshire Line at Pleck Junction, where it gave access to Walsall station. A station was opened on the Walsall spur called , this later closed in 1958.
