Chertsey Branch Line

The Chertsey Branch Line, opened in 1848, connects the Waterloo to Reading Line at Virginia Water to the South Western Main Line at Weybridge. It is also referred to as the Weybridge Line.

The line was electrified (660v DC third rail) on 3 January 1937 by the Southern Railway.

Stations on the line are:
 * Virginia Water
 * Chertsey
 * Addlestone
 * Weybridge

Services
On weekdays a half hourly all-stations service to London Waterloo station runs via Staines and the Hounslow Loop Line. Travel time may be shortened by a few minutes by changing to a fast train at Staines or Weybridge. On Sundays there is an hourly all-stations service which, instead of going to Weybridge, takes the west curve at Byfleet Junction and terminates at Woking. That curve is little used although from 2000 to 2002 the London Crosslink service of Anglia Railways from Colchester and Ipswich to Basingstoke via north London and Staines,  which used Class 170 DMUs, took it.

Lyne Railway Bridge
Between Virginia Water and Chertsey, the line crosses the M25 motorway by means of a cable-stayed bridge called Lyne Railway Bridge. (coordinates: 51.3931°N, -0.5324°W). The bridge is of note because it is one of the few such bridges in the world to carry a heavy railway. This is because the railway approaches the motorway at an angle of 28 degrees. The bridge consists of two concrete towers set into the central reservation of the motorway. The concrete edge beams are suspended from the towers, and each is supported by a pair of cables linked to the towers. The edge beams support a concrete deck slab on which the tracks run. The bridge is 120 yards (110 metres) long and 72 feet (22 metres) high, and was completed in 1979.
