An electric multiple unit used on the Victoria line of the London Underground

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 In the early 2000s, the reliability of service on the line was decreasing due to the age of the 1960s era Automatic Train Operation (ATO) system, and the 1967 Stock used on the line. Following the implementation of the London Underground Public Private Partnership in 2003, the Metronet consortium responsible for the infrastructure on the Victoria line began work on a substantial upgrade of the line. As part of the consortium, Bombardier Transportation would design, build and maintain the new rolling stock. In the 1990s, London Underground designed an open gangway "Space Train" with walk through carriages to increase capacity in the deep level tube. However, due to the technical risk and financial risk of not meeting the PPP contract requirements, Metronet ordered conventional trains from Bombardier in 2003, which were originally planned to enter service in 2006 at a cost of £750million.

The design of the trains was finalised in September 2004. Manufacture of two pre production trains began in early 2005, with the first scheduled to be completed by mid 2006. In February 2006, Metronet announced that the first of the pre production cars had been completed in preparation for static testing. From 21 July to 4 August 2006, a mock up of the train was on show at Euston Square Gardens, near Euston Square station, for a customer acceptance test followed by public display. From September 2006, the first pre production train underwent testing at Bombardier's manufacturing and test site at Derby Litchurch Lane Works. Metronet, the private consortium responsible for the infrastructure on the Victoria line, collapsed in July 2007 due to financial difficulties. Following negotiations with Bombardier, Transport for London took ownership of Metronet in May 2008, allowing for the upgrade to continue.

The second pre production train was expected to begin trial running in full passenger service in July 2008.

During the introduction of the trains, various teething issues with the new trains caused disruption on the line. During the morning rush hour on 21 July 2010, a train broke down at , and ambulances had to be called in to rescue almost 3,000 trapped passengers. Five days later, on 26 July 2010, another morning rush hour train broke down at , causing all Victoria line services to be temporarily suspended. Transport for London cited software failures and over sensitive door sensors as the main causes of both problems.

By the mid 2010s, the trains and signalling system were displaying exceptional levels of reliability, with the 2009 Stock travelling around six times further between failures than the 1967 Stock. A subsequent series of upgrades to the signalling system and track work allowed for an increase to frequency of service to up to 36 trains per hour, the most frequent in the UK and one of the most frequent in Europe. This was assisted by Metronet having ordered a larger train fleet than required. Compared to the 1967 Stock they replaced, the train has improved acceleration and a higher top speed of Braking performance is improved through the use of regenerative brakes, which save energy. >
