The Jubilee Line on the London Underground system opened in three stages during late 1999, making it the most recent addition to the London Underground. However the line connects a former line to new tunnelling.
The Jubilee Line starts in Stanmore and terminate in Stratford, serving 27 stations such as Wembley Park, West Hampstead, Baker Street, Green Park, Waterloo, London Bridge and Canary Wharf. The entire track is a distance of 22.5 miles.

The line from Stanmore to Baker Street already existed, as it had originally been part of the Bakerloo line. Tunnelling also existed between Baker Street and Charing Cross that could be incorporated into the line. The new tunnelling work began in 1992 between Green Park and Stratford and a new station was opened at Southwark in 1999.

At the present time, in 2007, as many as 405,000 people travel on the Jubilee line on a weekday, with annual figures of approximately 127 million passengers.
