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 December 2015, a total of 774 Aventra vehicles in 111 sets have been ordered, all by Transport for London.
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]
