The term "Metro-land" was coined by the Met's marketing department in 1915 when the "Guide to the Extension Line" became the "Metro-land guide". It promoted a dream of a modern home in beautiful countryside with a fast railway service to central London until the Met was absorbed into the London Passenger Transport Board in 1933., The Metropolitan line is a London Underground line that runs from Aldgate, in the City of London, to Amersham and Chesham in Buckinghamshire, with branches to Watford in Hertfordshire, and Uxbridge in the London Borough of Hillingdon.
