Aventra is a British family of electric multiple-unit passenger trains (EMUs) designed by Bombardier as a successor to the Electrostar EMUs.


The train has been designed to be lighter and more efficient, with increased reliability.[3] It will have lightweight all-welded bodies, wide gangways and doors to shorten boarding times in stations, and ERTMS.[2] The design incorporates FlexxEco bogies which have been used in service on Voyagers and newer Turbostars.[4] The gangway is designed to allow maximum use of the interior space and ease of movement throughout the train.[5][6]


As of June 2017, 2,180 carriages have been ordered for four operators:


The first order for Aventra trains covered 65 Class 345 9-car EMUs (with an option for 17 more) for the London Crossrail project. These will be operated by Crossrail concession holder TfL Rail.[7]

London Overground[edit]

London Overground has ordered 45 4-car trains (Class 710), with an option for 24 more, similar to those being used for Crossrail. They will replace class 315, 317 and 172s on London Overground Lea Valley and Gospel Oak lines as well as replacing the Class 378s currently operating on the Watford DC line and will be operated by London Overground concession holder Arriva Rail London.[8]

Abellio Greater Anglia[edit]

In August 2016, Abellio Greater Anglia was awarded the new East Anglia franchise, and announced an order with Bombardier for 22 ten-car trains and 89 five-car trains (a total of 665 carriages) as part of a full fleet replacement programme.[9]

South Western Railway[edit]

On 20 June 2017, Bombardier was awarded a contract to build 750 cars for South Western Railway. These will be formed into 30 five-car and 60 ten-car sets and replace its 455, 456, 458 and 707s.[10][11]
