With the Coradia Polyvalent, Alstom offers a multiple unit that is available purely electric or as a dual-powered train with diesel and electric drive. As is typical for the Coradia, the entire drive technology, including the diesel engines, is located on the roof. Various versions are available for use on suburban routes, in regional traffic and in intercity traffic. From the framework contract for 1,000 trains, the SNCF called off 387 units as “Régiolis” until 2020. 17 and 15 trains respectively were also sold to Algeria and Senegal. The trains are now being produced and further developed by CAF. In the future, the diesel engines will be replaced by batteries, and a fuel cell drive is also under development.
