Baker Street tube station in the context of "St John's Wood tube station"

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.

Finchley Road is a London Underground station at the corner of Finchley Road and Canfield Gardens in the London Borough of Camden, north-west London. It is served by the Jubilee and Metropolitan lines, and is in London fare zone 2. On the Jubilee line, the station is between West Hampstead and Swiss Cottage stations. On the Metropolitan line, it is between Wembley Park and Baker Street stations.

The station is located 100 yards (91 m) south of the O2 Centre. It serves the Frognal and South Hampstead areas. It is also a five-minute walk from the Finchley Road & Frognal station on the London Overground's Mildmay line, and this is marked as an official out-of-station interchange. The station is in a cutting covered by a single glass and metal canopy and is the northernmost station below street level on the line.
