The Ruislip Lido Railway is a 12-inch (305-mm) gauge miniature railway, running around the popular tourist attraction of 'Ruislip Lido' in Ruislip. The railway runs along a 1.5-mile (2.4-km) track around the lake and through the Ruislip woods. It started operation around 1945, with short trains being hauled by "Prince Edward" an Atlantic type steam locomotive over a line about a third of its current length.

The railway was built by the Grand Union Canal Company as part of the leisure facilities at the Ruislip Lido which is a reservoir for the canal. When the Grand Union was nationalised in 1948 to be part of the British Transport Commission, control of the Lido and its railway passed into the hands of Ruislip-Northwood Urban District Council which, in 1965, became part of the London Borough of Hillingdon. Under local authority control the railway was neglected and, following an accident in 1978, it was closed. In 1980, the volunteer run Ruislip Lido Railway Society Limited reopened the railway using a petrol powered engine and gradually expanded the route around the Lido and added additional rolling stock. With Pinewood Studios nearby, the Lido has been used as a filming location for scenes in a number of films including The Young Ones starring Cliff Richard. (Full article...)
