Staines and West Drayton Railway

The Staines & West Drayton Railway (S&WDR) is a former railway on the western edge of London, England. It was about 5+1/2 mi long and ran roughly north-south along the River Colne. It opened from West Drayton on the Great Western Main Line to Colnbrook in 1884 and reached Staines the next year.

Passengers
By 1961 it had five intermediate stations but the area is sparsely populated, as it is in the flood plain of the river Colne and there are large reservoirs on both sides of the line, and local passenger traffic failed to develop. The line closed to passengers in March 1965.

Connections
The promoters had wanted a connection at Staines to the London and South Western Railway but that company would not allow the Great Western Railway access and the S&WDR terminated at a separate station, converted from a Georgian house. A connection of sorts between the two lines developed through the sidings and turntables of the Staines Linoleum Company's factory but the first purpose-built link was a curve laid in 1940 from Staines Moor Junction some three chains south of Yeoveney Halt to an east-facing connection on the Southern Railway east-bound route to give a diversionary route should central London north-south routes be cut by bombing.

Northern section
Freight trains still run from West Drayton to Colnbrook serving an aggregates depot and an aviation fuel terminal for Heathrow Airport.

Southern section
The section south of Colnbrook to the bridge over the Southern's line from Staines to Windsor was abandoned in 1981 as part of the route was required for the construction of the M25 motorway. Between Colnbrook and Staines Moor the track has been lifted and the formation built over in several places. Part of the viaduct at Staines Moor is used as a footpath. A fuel oil terminal had been built in the 1960s at the former goods yard at Staines West. Simultaneously with the closure of the line south of Colnbrook in 1981 a new connecting line was built for it to the Staines to Windsor & Eton Line and this was used until closure in 1991.

Airtrack-Lite
The proposed Airtrack-Lite rail link from Heathrow Airport through Staines would entail laying track near the former southern part of the S&WDR route.
