The Wolverhampton–Shrewsbury line is the railway line from Wolverhampton to Shrewsbury via Wellington; it was originally built by the Shrewsbury and Birmingham Railway. The line is double track throughout, with rarely used relief sidings at Cosford and four tracks through Wellington station.

The Shrewsbury and Birmingham Railway was authorised in 1846. It agreed to joint construction with others of the costly Wolverhampton to Birmingham section, the so-called Stour Valley Line. This work was dominated by the hostile London and North Western Railway, which used underhand and coercive tactics. The section between Shrewsbury and Wellington was also built jointly, in this case with the Shropshire Union Railway.
