Hydrogen propulsion will play an important role, and this project with Alstom will demonstrate how the private sector can work together to make a difference." Alstom and Eversholt Rail have previously collaborated on the 'Breeze' project — a hydrogen rolling stock solution for the UK rail sector, through the proposed conversion of an existing electric multiple unit (EMU) to hydrogen power. Both companies now believe that there is a market for a fleet of new trains for use by train operators around Britain. The breadth, depth of knowledge and experience gained from the Breeze project, together with stakeholder feedback on future fleet strategies, has been invaluable in shaping the product planning. Building on Alstom's long expertise in keeping Britain moving, the Aventra single-deck train has been developed for the requirements of mainline train operations, from high-capacity metro systems to intercity services.
