The Wessex Route is one of the busiest and most congested routes on the rail network. With 1,300 miles of track and over 200 stations, it includes the major commuter area of south west London as well as providing long distance services from Waterloo to the south and south-west of England, including all or part of the counties of Surrey, Berkshire, Hampshire, Dorset, Somerset and Wiltshire.
Wessex contains some of the most densely trafficked railway lines in the country and is vital in supporting long distance traffic to and from other regions on its main lines. Significant urban areas on the route include Aldershot, Bournemouth, Southampton, Portsmouth, Guildford, Woking and Basingstoke. The network carries passenger services and significant volumes of freight traffic, linking Southampton Port and Airport with the Midlands and North of England, and is used by a number of operating companies.
