By 1871, when the District began operating its own trains, the railway had extended to West Brompton and a terminus at Mansion House. Hammersmith was reached from Earl's Court and services reached Richmond, Ealing, Hounslow and Wimbledon. As part of the project that completed the Circle line in October 1884, the District began to serve Whitechapel. As a result of the expansion, by 1898, 550 trains operated daily. Services began running to Upminster in 1902, after a link to the London, Tilbury & Southend Railway had been built.
