... originally connected the main line termini at Paddington, Euston and Kings Cross to Farringdon in the City of London. It was soon extended at both ends, and northwards via a branch from Baker Street. It reached Hammersmith in 1864, Richmond in 1877, and completed the Inner Circle in 1884, but the most important route was the line north into the Middlesex countryside, where it stimulated the development of new suburbs. Harrow was reached in 1880, and the line eventually extended to Verney Junction in Buckinghamshire, more than 50 miles from Baker Street and the centre of London.
Former Metropolitan Railway tracks and stations are now used by the London Underground's Metropolitan, Circle, District, Hammersmith & City, Piccadilly, and Jubilee lines, and by Chiltern Railways.
