The Keighley & Worth Valley Railway (KWVR) is a preserved five-mile-long standard-gauge branch line, linked to the national railway network at Keighley in West Yorkshire, which reopened in June 1968 following its closure by British Railways in 1962. The railway featured in the 1970 film The Railway Children, and serves Haworth, the village that was famously home to the Brontë sisters.

The KWVR issued its own railway letter stamps between 1979 and 1990.
