The UK’s Transport for London (TfL) is set to award a £260m contract to Bombardier Transportation to deliver of new fleet of trains for customers on London Overground routes in East and North-East London.
Under the deal, which is subject to a statutory ten-day standstill period, Bombardier will supply 45 new air-conditioned trains, which are scheduled for delivery in 2018.
The new fleet will operate on the Liverpool Street to Enfield Town, Cheshunt (via Seven Sisters) and Chingford routes, which became part of the TfL network in May.
They will also be run on the routes between Barking and Gospel Oak, and between Romford and Upminster.
The new trains will be built in Derby supporting hundreds of jobs in the area, including more than 20 apprenticeships.
London mayor Boris Johnson said: "This brand new fleet of trains will enable London Overground to carry a growing number of passengers more reliably and speedily than ever.
"By investing in new trains here in the capital, TfL is helping to support jobs and skills in Derby and right across the country."
A total of 31 new trains will replace the existing Class 315 and Class 317 trains currently in service on the Overground West Anglia and Romford to Upminster routes.
The company will supply eight new four-carriage trains for the electrification of the existing Overground route between Gospel Oak and Barking.
The Gospel Oak to Barking line, already part of London Overground, is currently being electrified by Network Rail and scheduled to be completed in 2017.
These new four-carriage electric trains will replace all of the two-carriage Class 172 diesel trains, and will provide improved journey times and more capacity.
Tfl said that additional six trains will strengthen services on other Overground routes.
