Derby-based train manufacturer has officially signed the £1 billion contract to provide 65 new trains for the new Crossrail line in London.
The new deal has secured the future of around 760 jobs, and means the creation of 244 new positions at the new depot.
Transport Secretary Patrick McLoughlin said welcomed the official sealing of the deal.
Derby has a deserved reputation for quality train building and I am delighted Bombardier can write the latest chapter in this success story.
The deal is a win for the employees of Bombardier and British manufacturing, supporting 760 new jobs and 80 apprenticeships.
For commuters it will mean new state-of-the-art trains that deliver quicker and more comfortable journeys and boost capacity across the capital.
