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 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. This was built beneath the New Road using the "cut-and-cover" method between Paddington and King's Cross and in tunnel and cuttings beside Farringdon Road from King's Cross to Smithfield, near the City. When this line opened to the public on 10 January 1863, with gas-lit wooden carriages hauled by steam locomotives, it was the world's first underground railway
