History
Baker Street is the world's first underground railway.
The world's first underground railway was the Metropolitan Railway, which opened in London on 10 January 1863. Baker Street was one of its original stations, but the claim that Baker Street itself is the first underground railway is misleading. The railway as a whole holds that distinction.
