Tube Lines Limited, initially known as Infraco JNP, was an asset-management company responsible for the maintenance, renewal and upgrade of the infrastructure, including track, trains, signals, civils work and stations, of three London Underground lines.

Wembley Park is a London Underground station in Wembley Park, north west London. The station is served by the Jubilee and Metropolitan lines and is in Travelcard Zone 4. It is located on Bridge Road (A4089) and is the nearest Underground station to the Wembley Stadium and Wembley Arena complex. This is where the Jubilee line from Stanmore diverges from the Metropolitan line, which was formerly a branch of the Metropolitan Railway and was taken over by the Bakerloo line and today part of the Jubilee line.
