The London Underground 2009 Stock is a type of London Underground train built by Bombardier as part of its Movia family at its Derby Litchurch Lane Works, England. A total of 47 eight-car trains have been built for the Victoria line. They entered service between July 2009 and June 2011 and replaced the 1967 Tube Stock. It is the first new deep level tube stock on the Underground network since the 1996 Stock entered service on the Jubilee line in 1997.

Metronet Rail was an asset-management company responsible for the maintenance, renewal and upgrade of the infrastructure, including track, trains, signals, civils work and stations, on several London Underground lines. It was one of two infrastructure companies in a public-private partnership (PPP) with the Underground.
