branch services were then transferred to the Bakerloo line, with effect from 20 November 1939, and diverted to run into Baker Street in the new tunnels, thus reducing the number of trains using the Metropolitan line's tracks. For the new deep-level route, a new Bakerloo line station named Swiss Cottage was opened adjacent to the existing Metropolitan line station. For a time, they operated as a single station (platforms 1 and 2 were for the Metropolitan line, and platforms 3 and 4 were for the Bakerloo line). This arrangement was short-lived, however, and the Metropolitan line Swiss Cottage station was closed after the last train on 17 August 1940 as a wartime economy. On 1 May 1979, the Stanmore branch of the Bakerloo line was transferred to the new Jubilee line. The MR station building was demolished in the 1960s to allow the widening of Finchley Road, but the former platform area still exists in part. Unbuilt line to Hampstead Before the line was constructed, the M&StJWR received authorisation in 1865 to continue the line northwards from Finchley Road to a station at Hampstead. This appeared on some maps. The scheme was cancelled in 1870. A section of tunnel was built north of Swiss Cottage station for the Hampstead extension, most of which was used for the later extension to the north-west. A short length towards Hampstead was unused. This is still visible today when travelling on a southbound Metropolitan line service.
