Aventra has been designed to accommodate large numbers of passengers for city centre metro-style operations and longer outer suburban journeys; it features a gangway design that allows maximum use of the interior space and ease of movement throughout the train.<ref name=RailEngineer>{{cite web|url=http://content.yudu.com/Library/A1mz4o/RailEngineerMarch201/resources/29.htm|accessdate=2011-04-01|title=The customer is king|publisher=Rail Engineer}}</ref> This new design is already in use on the [[Class 378]] rolling stock used by [[London Overground]].

The Class 378 is currently the lightest train in its class. However, ''AVENTRA'' is expected be 10 tonnes lighter, partly due to the aluminium structural components,<ref>http://www.rail.co/2011/03/21/bombardiers-aventra-a-new-era-in-train-performance/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed:+Railco+%28rail.co%29</ref> used on other vehicles from which Aventra has evolved. Bombardier claims the new train will be 70 per cent more reliable than the best available today, enabling faster journeys and using up to 50 per cent less energy than the Class 319s, which currently operate on the Thameslink services. A ‘driver assistance system’ will take into account gradients and real-time route conditions, to advise the driver how best to minimise power consumption while still meeting the timetable. Trials using a Class 365 brought a 13 per cent energy saving. Unlike today’s commuter trains, ''AVENTRA'' will also shut down fully at night and can be ‘woken up’ by remote control before the driver arrives for the first shift.<ref>http://www.railpro.co.uk/magazine/archive/PDFs/dec09_FULL.pdf</ref>

==Display System==
Using Bombardier [http://www.bombardier.com/en/transportation/products-services/services/innovation---technology?docID=0901260d8001a9b7# Orbiflo] to provide up-to-date passenger information also enables the Passenger Information System to display departure details for station or airport connections. Another advanced facility is to provide advice on seat availability based on loading, guiding passenger to vehicles with more space. The PIS can also deliver information to the passenger through audio or video message tailored specifically to the route travelled.<ref name=RailEngineer/>

==Energy Saving==
{{contradict|date=July 2011}}
The design includes two independent [[HVAC]] systems - one for the saloon and the vestibules and the other for the driver's cab. Energy saving techniques have been implemented in the HVAC design and control with a view to optimising power consumption and fresh air cooling, as well as regulating the internal temperature based on the number of occupants. The weight saving from using a single unit (rather than two as on the Electrostars) is expected to be about 200kg per car, which when combined with the simplified roof construction, provides an overall weight reduction of approximately 30 per cent.<ref>http://content.yudu.com/Library/A1mz4o/RailEngineerMarch201/resources/29.htm</ref>

The Aventra is a new family of EMUs designed by Bombardier as a successor to the Electrostar EMUs.

Description

The multiple units have been designed to be lighter, more efficient, and have increased reliability.[3] They 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 Meridians.[4]

The design features a gangway design that allows maximum use of the interior space and ease of movement throughout the train.[5] [6]
