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

Description

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]

Orders

As of October 2016 a total of 1434 individual vehicles have been ordered for three different operators:

Crossrail

The first order for Aventra trains covers 66 Class 345 9-car EMUs (with an option for 17 more) for the London Crossrail project.[7]

London Overground

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 British Rail Classes 315, 317 and 172 on London Overground Lea Valley and Gospel Oak lines as well as replacing the Class 378 units currently operating on the Watford DC line.[8]

Abellio Greater Anglia

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 as part of a full fleet replacement programme.[9]
