 From 1 August 1872 , the Middle Circle service also began operations through South Kensington , running from Moorgate along the MR 's tracks on the north side of the Inner Circle to Paddington , then over the Hammersmith & City Railway ( H & CR ) track to Latimer Road , then , via a now demolished link , on the WLEJR to Addison Road and the DR to Mansion House . The service was operated jointly by the H & CR and the DR. On 30 June 1900 , the Middle Circle service was shortened to terminate at Earl 's Court , and , on 31 December 1908 , the Outer Circle service was withdrawn from the DR tracks . As part of efforts to improve competitiveness , the DR 's tracks were electrified during 1905 and new electric rolling stock was brought into use . In 1907 , the station was given its present name , Westminster .
