The Jubilee line is a London Underground line that runs between Stratford in east London and Stanmore in the suburban north-west, via the Docklands, South Bank and West End. Opened in 1979, it is the newest line on the network, although some sections of track date back to 1932 and some stations to 1879.

The western section between Baker Street and Stanmore was previously a branch of the Metropolitan line and later the Bakerloo line, while the newly built line was completed in two major sections: initially in 1979 to Charing Cross, then in 1999 with an extension to Stratford.

The main servicing and maintenance depot on the Jubilee line is Stratford Market Depot between the Stratford and West Ham stations.Trains are also stabled in Neasden Depot – sharing it with the Metropolitan line.

Stratford Market Depot was built as part of the Jubilee Line Extension in the late 1990s, as the Neasden Depot could not accommodate the increased number of trains required.

There are 27 stations and the line is 22.4 miles long.
