English: Queen's Park railway station The station serves both the Bakerloo Line and London Overground trains. The original Baker Street and Waterloo Railway (hence Bakerloo) opened in 1906 to Baker Street and was extended here to Queen's Park in 1915. The service was then extended to Watford Junction, only to be subsequently terminated. Since 1989 Bakerloo Line trains have run northwards as far as Harrow and Wealdstone station. Here a southbound Bakerloo Line train is about to depart for Elephant & Castle. By a quirk of the geometry of the railway line, and demonstrating the schematic nature of the classic Underground map, northbound Bakerloo Line trains leaving Queen's Park for Kensal Green actually travel more southwards than northwards, whereas the map shows the line heading due north.
