The 2009 Tube Stock is a type of London Underground train built by Bombardier as part of its Movia family at its Litchurch Lane Works in Derby, England. A total of 47 eight-car units have been built for the Victoria line, entering passenger service between July 2009[1] and June 2011 and replacing the 1967 Tube Stock.[2]

The trains are part of a £3.4 billion contract awarded by the now-defunct Metronet to Bombardier to supply new trains featuring Automatic Train Operation and signalling for the Victoria line and other sub-surface lines.[3] This upgrade, when completed in 2012,[4] is expected to provide improved reliability, an 8% decrease in journey times between stations, and a 16% overall decrease in journey times.[5] This is due in part to the trains having better performance than the 1967 Stock they replaced - they have a higher top speed of 80 km/h (50 mph), a faster maximum acceleration of 1.3 m/s2 (4.3 ft/s2), a normal service deceleration of 1.14 m/s2 (3.7 ft/s2), and an emergency brake deceleration of 1.4 m/s2 (4.6 ft/s2), the same as the 1992 Tube Stock.[6] At peak times, 43 trains should be in service, an increase of six over the 1967 Stock.[7]

The trains are 40 mm (1.57 in) wider than the 1967 Stock to take advantage of the Victoria line's loading gauge, which is slightly larger than those of other deep-level tube lines.[8] This, however, prevents them from leaving the Victoria line, except by road.[9] The trains seat 252 and have standing space for an estimated 1,196 passengers, giving a 19% increase in capacity over the 1967 Stock.[5] They also have wider doors for easier boarding and alighting of passengers in order to reduce dwell times in stations.[4] The trains have been built with Bombardier's FICAS technology, giving a thinner bodyshell and hence (along with the larger size) more internal space for passengers.[10] They are the first London Underground trains to be designed since the Rail Vehicle Accessibility Regulations were introduced,[11] so they have more facilities for people with impaired mobility, including multi-purpose areas with tip-up seats and space for wheelchairs and pushchairs,[12] and offset centre door poles for wheelchair access.[13]

The trains are the longest deep-level tube trains on the system at 133.275 m (437 ft 3 in), 3 m (9 ft 10 in) longer than the 1967 Stock[8] (although the new sub-surface S Stock, which is also part of Bombardier's Movia family and has been ordered under the same contract, is longer still).[8] They are said to use a modified version of the traction pack used on Bombardier's Electrostar trains.[14] They have CCTV cameras[5] and dot-matrix displays to show real-time service information as well as audio announcements.[8] They maintain a fixed height to keep the train in profile under different loading patterns and regardless of the extent of wheel wear.[15] Unlike most other London Underground trains, they have their Combined Traction/Brake Controller (driver's manual controls, often called "dead man's handle") on the right-hand side of the cab,[16] as most of the platforms on the Victoria line are on the right.[16] Access to the cab for driver changes is easier than on the 1967 Stock: an external side door is fitted,[17] whereas the cab in the 1967 Stock had to be accessed through the passenger compartment, which could be difficult at rush hour.[18]

Each train is made up of two 4-car units of the configuration Driving Motor - Trailer - Non Driving Motor - Uncoupling (Shunting) Non Driving Motor,[19][20] which are coupled back-to-back. The trains are maintained at the Victoria line's Northumberland Park Depot, with Bombardier staff on site for warranty parts replacement.[21] They were originally intended to have all-motored axles as in the 1992 Stock, so that they would have enough traction and acceleration for faster running times; however, it was later decided that 75% of motored axles would be sufficient,[22] which reduced project costs by around £10 million[23] (about 3.5% of the overall cost[24]). They have mechanical-only Scharfenberg couplers.[25]

Introduction into service[edit]

The design of the trains was finalised in September 2004. Manufacture of two pre-production trains began in January 2005, the first scheduled to be completed by mid-2006.[2] On 3 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 tube 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 its Litchurch Lane Works in Derby.[8] It was due to be delivered to London Underground by the end of 2006 for testing on the Victoria line during engineering hours[2] but this did not occur until May 2007.[8] It was also used for driver and maintenance training and familiarisation.

The second pre-production train was also tested on the Victoria line during engineering hours, and was expected to begin trial running in full passenger service in July 2008.[8] However, this date slipped twice, first to January 2009[26] and then to July 2009. The train finally entered service on 21 July 2009, leaving Northumberland Park depot at 23:00[27] and forming the 23:55 service between Seven Sisters and Brixton.[1]

Main production commenced at the end of 2009, with one train entering passenger service every two weeks from February 2010. By mid-2011, there was a sufficient number of trains in service to allow the withdrawal of the few remaining 1967 Stock trains, the last of which ran on 30 June 2011.

Problems[edit]

During the morning rush hour on 21 July 2010, a train broke down at Pimlico, 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 Oxford Circus, 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.[28][29] A new sensitive door edge, branded Intelligent Sensitive Edge, is being developed by the Victoria line engineers to overcome this problem, and TfL hopes to install it across the stock at a cost of around £3 million.[citation needed]

Roster[edit]

Individual cars of the 2009 Stock have a five-digit number. The second digit identifies the role of car and the last three digits identify the set number (Numbers 001 to 094). A end units have odd numbers while D end units have even. The numbering system of the 2009 stock upon introduction is as follows:
