The District Line is amongst the oldest lines on the London Underground and includes the original section of the network between South Kensington and Westminster which opened in December 1868. First called the Metropolitan District Railway, the plan was to create a below-ground ‘inner circle’ connecting London’s railway termini. The line was developed with branches and extensions over the next 30 years and by 1902 it had extended eastwards as far as Upminster with further changes being made throughout the 20th Century.
