Camden Town tube station is a major junction on the Northern Line and one of the busiest stations on the London Underground network. It is particularly busy at weekends with tourists visiting Camden Market and Camden High Street.
The station began life as part of the original route of the Charing Cross, Euston and Hampstead Railway (now part of the Northern Line). As the line here branched into two routes, to Hampstead and to Highgate, the design of the station was rather unusual, shaped like a V. The line to Hampstead (now the Edgware Branch) is under Chalk Farm Road; the line to Highgate (now the High Barnet branch) is under Kentish Town Road. With the narrowness of the roads above, and the necessity to keep directly beneath them to avoid having to pay compensation to landowners during construction, on both lines the northbound platform is directly above the southbound one.
