The Old Kiln Light Railway is a 2 ft (610 mm) narrow gauge railway at the Rural Life Centre open-air museum in Tilford, near Farnham, Surrey. It has a collection of historic locomotives and rolling stock including two steam locomotives. 

Founded in the early 1970s as a heritage "Wey Valley Light Railway", it was first located around a disused pumping station in Farnham. In 1982 the land was sold for housing and the track and equipment were moved to the Old Kiln Museum, now known as the Rural Life Centre. The line has since lengthened around the centre and a small stretch of track serves the museum's heritage timber yard demonstration area.
