Today we look at the now defunct line from Watford Junction to Rickmansworth. The Watford and Rickmansworth Railway (W&RR) ran services between Watford and Rickmansworth in Hertfordshire, England. The company was incorporated in 1860; the line opened in 1862. The Rickmansworth branch was closed in 1952, and the remaining line was gradually run down and eventually closed in 1996. Route map. Older versions of Watford Junction and Watford High Street would need to be included, followed by... Croxley Mills Junction. Rickmansworth Church Street station.
