Clapham Junction

Area in the western borough of Wandsworth in London, England, centred on the eponymous railway junction and station on St John's Hill in the southwest district of Battersea. The locality's development and characteristics reflect the influence of the station. Clapham Junction is the UK's busiest railway station, with over 2,500 trains passing through it daily. As a result of the frequent links both in and out of the city centre, Clapham Junction has become a popular area for people to live, with an accompanying selection of shops, bars, and restaurants.

Northcote Road is famous for its host of bars, restaurants, and antique shops, while other shopping areas are located on St John's Road, and at the crossing with St John's Hill and Lavender Hill. On this corner is the historic Arding & Hobbs department store (1885), which was rebuilt, after a 1909 fire, to include its landmark cupola. Prior to the railway age, the area was rural and specialized in the growing of lavender. The station encouraged the development of the area around it, with the population rising from 6,000 people in 1840 to 168,000 by 1910.

In December 1988, Clapham Junction – at a point just east of the station – was the scene of a railway accident involving two collisions between three commuter trains, in which 35 people died and more than 100 were injured.
