London Underground 2009 Stock

The **London Underground 2009 Stock** is a type of London Underground train. It is built by Bombardier Transportation at their Litchurch Lane Works in Derby, England. The stock belongs to Bombardier's *Movia* type of train. Bombardier Transportation UK used to be known as ADtranz, and before that ABB Asea Brown Boveri. ABB Asea Brown Boveri built the 1992 tube stock which is currently used on the Central and Waterloo & City lines.

Forty-seven 8-car units will be built for use on the Victoria line. These replace the line's original 1967 tube stock. The trains are still being built. They were introduced by 2012, when all of the 1967 tube stock trains were completely replaced. The first 2009 tube stock train started running on the line with passengers on board on 21 July 2009. One new train will enter service every two weeks from early 2010.

## Description 
The trains are part of a 3.4 billion pound contract that was awarded to Bombardier by Metronet. The contract was to supply new trains featuring Automatic Train Operation and signalling for the Victoria and sub-surface lines. When it is finished this upgrade should make the lines and trains more reliable. There should also be an 8% decrease in journey times between stations, and a 16% overall decrease in journey times. This decrease is partly because the new trains have better performance than the 1967 tube stock that they are replacing. The new trains have a higher top speed of , a faster maximum acceleration of 1.3 m/s2, a normal service deceleration of 1.14&nbsp;m/s2, and an emergency brake deceleration of 1.4&nbsp;m/s2. This is the same as the 1992 tube stock.

During the busiest times of the day, or the "peaks", 43 trains should be available in service. This will be an increase of 6 trains over the 37 units of 1967 tube stock. This means that to move the units, each car has to be , loaded onto a lorry, and then re-coupled when they are delivered. The trains have been built using Bombardier's technology called FICAS, which gives them a thinner . Along with the larger size this gives more space for passengers.

The stock is the first to be designed since the Rail Vehicle Accessibility Regulations came into force. Because of this they will have more facilities for people with impaired mobility, including multi-purpose areas with tip-up seats and space for wheelchairs and pushchairs and offset centre door poles for wheelchair access.

## Introduction 
The design of the trains was finalised in September 2004, and manufacture of two pre-production trains began in January 2005. The first train was scheduled to be completed by mid-2006. The first train entered service on 21 July 2009, leaving Northumberland Park depot at 23:00 and forming train 277 leaving Seven Sisters at 23:55 to Brixton.
