The London Underground opened on 10 January 1863 when the Metropolitan Railway (nowadays the Metropolitan line) opened 7 stations between Paddington and Farringdon. The first station known constructed was Baker Street (named after William Baker) and this station is known for the Sherlock Holmes home nearby.

In 1868, the District line (back then called Metropolitan District railway and then called District Railway) opened and the Metropolitan Railway and the District became known as the Metropolitan District Railway.
