Four Avelia Euroduplex trains from the SNCF fleet will enter commercial service on Monday 10 May 2021 on the Madrid-Barcelona route. They will be operated by OUIGO España, a local subsidiary of SNCF. The trains have been converted by Alstom and SNCF to run on the Spanish high-speed rail network.

Following on from these first four trains, 10 other trains are currently being converted by Alstom to serve several high-speed routes in Spain: initially, the Madrid-Valencia and Madrid-Alicante routes and subsequently, Andalusia (Madrid-Seville and Madrid-Malaga). OUIGO España will thus have a fleet of 14 trains for 5 destinations departing from Madrid: Barcelona, Valencia, Alicante, Seville, and Malaga.

During the conversion process of the trains, Alstom developed and deployed on-board signalling equipment architecture, necessary for rail traffic safety and performance, based on its digital ERTMS[1] solution Atlas. This solution ensures that Avelia Euroduplex trains are compliant and can be approved for Spanish infrastructures.
