“The Metropolitan Railway (also known as the Met) was a passenger and goods railway that served London from 1863 to 1933, its main line heading north-west from the capital’s financial heart in the City to what were to become the Middlesex suburbs. Its first line connected the main-line railway termini at Paddington, Euston, and King’s Cross to the City.
The first section was built beneath the New Road using cut-and-cover between Paddington and King’s Cross and in tunnel and cuttings beside Farringdon Road from King’s Cross to near Smithfield, near the City. It opened to the public on 10 January 1863 with gas-lit wooden carriages hauled by steam locomotives, the world’s first passenger-carrying designated underground railway.
The line was soon extended from both ends, and northwards via a branch from Baker Street. Southern branches, directly served, reached Hammersmith in 1864, Richmond in 1877 and the original completed the Inner Circle in 1884. The most important route was northwest into the Middlesex countryside, stimulating the development of new suburbs. Harrow was reached in 1880, and from 1897, having achieved the early patronage of the Duke of Buckingham and the owners of Waddesdon Manor, services extended for many years to Verney Junction in Buckinghamshire.”
