The Rugby to Leamington Line was a railway line running from Rugby to Leamington Spa. It was a 15-mile (24 km) branch line built by the London and North Western Railway (LNWR) and opened in 1851. The branch connected Leamington with the mainline from London to Birmingham (now the West Coast Main Line) which had been opened in 1838 by the LNWR's predecessor, the London and Birmingham Railway (L&BR).
