The Slough to Windsor & Eton Branch Line is a railway line, approximately 2.5 miles (4.0 km) long, in Berkshire, England. Trains run between the line's only two stations, Slough and Windsor and Eton Central. At its northern end, the branch line joins the Great Western Main Line, but passenger trains from Windsor rarely use the connection, terminating instead at Slough.

Services

A 20-minute service interval in each direction is operated by Great Western Railway using the dedicated bay platform 1 at Slough.

Rolling stock

Neither the Great Western Main Line west of Hayes and Harlington nor its branch lines are electrified and most trains on the Windsor Branch are diesel-powered.

Services are provided by Class 165 and Class 166 2- and 3-car diesel multiple units (DMUs).

In the 1970s and 1980s DMUs such as the Class 117 and Class 121 ('Bubblecars') were used.

Electrification

Electrification of the Slough to Windsor route was approved in 2014.^[1]

The line opened, despite opposition from Eton College, on 8 October 1849. It was built as a broad gauge line but dual gauge track was laid in 1862.^[2]

For a period from 1863, Metropolitan Railway trains served the line. Between 1 March 1883 and 30 September 1885 the branch was also served by the Metropolitan District Railway.

Slough Junction

Slough Junction^[3] was a triangular junction connecting the branch line to the mainline in both eastbound (towards London) and westbound (towards Reading) directions. It is not known whether it was used for turning complete trains; a turntable was available at Slough shed for turning locomotives. The layout of the junction was complicated, as the east curve ran between sidings of the shed.

Most service trains accessed Slough station by the eastern chord, which remains in use. It is double track, with the "outer" track to the bay platform used by branch-line trains at Slough, and the "inner" track, connected to the mainline, used by empty stock workings and by rare passenger trains.

The western chord, known as the "Royal" or "Queen's" Curve, was little used except by excursion traffic and royal trains (hence its nickname). It was closed through lack of use in 1964 and was used for a time to stable carriages, after which the track was lifted.

All land west of the eastern chord was sold for housing, and there is little evidence of the junction at the site now although aerial photographs show the curving line of the western tracks.

Chalvey Halt

The only intermediate stop on the branch line was Chalvey Halt,^[4][5] 47 chains (945 m) south of Bath Road Junction.^[6] The halt was authorised on 24 February 1929, at an estimated cost of £840, and opened on 6 May 1929. It comprised both "up" and "down" platforms, built from heavy timbers to the standard GWR design for halt platforms. There were also waiting shelters, and steps down to the nearby road.^[7]

After only 14 months of operation, Chalvey Halt closed on 7 July 1930. A note in the GW Engineer's Department minutes of 19 October 1930, records that the materials from Chalvey Halt had been used to build Cashes Green Halt on the Gloucester to Swindon "Golden Valley Line", between Stroud and Stonehouse.^[8]
