Alstom Aventra
The Alstom Aventra (sold as the Bombardier Aventra until 2021) is a family of electric multiple unit (EMU) passenger trains produced at Derby Litchurch Lane Works in the United Kingdom, originally by Bombardier Transportation and later by Alstom, as a successor to the Bombardier Electrostar. A large proportion of its design is based on the Electrostar, adding new technologies and achieving compliance with more stringent requirements and operator demands.

Bombardier began developing the Aventra in 2009 based on feedback from train operating companies (TOCs) and upcoming regulation changes. It has been designed to provide a generic platform for conducting inter-regional, commuter, metro, and high-speed passenger services. It has been claimed to be more efficient and flexible than the Electrostar, which was mainly achieved via the greater use of digital technology. The development of a bi-mode version of the Aventra, incorporating batteries, was proposed as a replacement for existing diesel multiple-units.
The first order for the Aventra came from the Crossrail programme in 2014. Numerous other operators have since ordered the type, including London Overground, Greater Anglia, South Western Railway, c2c and West Midlands Trains.
