Staines to Windsor Line

The Staines to Windsor Line is a National Rail suburban railway line in England operated by South West Trains. It branches from the Waterloo to Reading Line at Staines-upon-Thames in Surrey and runs to Windsor in Berkshire.

History
The line from Richmond through Staines to Datchet was opened on 22 August 1848 by the Windsor, Staines and South Western Railway under the auspices of the London and South Western Railway(L&SWR) and reached Windsor on 1 December 1849. The line was electrified in 1930 at 660v DC (since raised to 750v) on the third rail system by the Southern Railway.

Connections to Staines West Branch
The L&SWR opposed connection with the Staines West Branch but three separate connections have existed. The earliest was through the sidings of the Staines Linoleum Company and would have required use of turntables or reversals to pass wagons between the lines. In World War II a single track spur was laid from just south of Yeoveney Halt facing up on the Staines to Windsor Line as a diversionary route should cross-London routes be blocked by bombing, this link existed from 23 June 1940 to 16 December 1947 but was little used. The last, laid in 1981 when the Staines West Branch was severed by the M25 motorway, was to an oil terminal built in the former goods yard of Staines West station and lasted until 1991.

Services
The service frequency is two trains per hour in each direction every day except early on Sunday mornings when it is one per hour. From Windsor to London Waterloo takes about 55 minutes, some 20 minutes longer than the quickest journeys to London Paddington from the other station at Windsor, Windsor & Eton Central, although according to Network Rail timetables, the journey time to many central London locations is similar from both stations.

Services on the line run beyond Staines to London Waterloo, running a fast service which calls at these stations:
 * Ashford
 * Feltham
 * Whitton
 * Twickenham
 * Richmond
 * Putney
 * Clapham Junction
 * Vauxhall
 * London Waterloo

Current eight-car passenger trains are too long for the platforms at Sunnymeads and Datchet; passengers for those stations need to travel in the front four coaches.

AirTrack
A 2008 proposal, since dropped, was for the AirTrack rail link to have a station near the site of the former Staines High Street railway station.
