The TGV M ("M" for modular, also known as the Avelia Horizon) is a high-speed passenger train designed and produced by Alstom. It has a broadly similar design to the TGV Duplex sets, with bi-level carriages and a push–pull configuration with a power car on either end. However, it is more energy efficient and provides lower operating costs.[2]
Development of the TGV M originated with SNCF's launch of a program to procure a new generation of high-speed trains in 2015. In May 2016, the Alstom-headed Speedinnov joint venture was selected as the winning bidder for the program; on 7 September 2016, SNCF and Alstom signed an agreement to design and build the new trains. In July 2018, SNCF placed an initial €2.7 billion order for 100 trainsets, then referred to as the Avelia Horizon. Production of the first bodyshells commenced in mid-2020; two years later, dynamic testing was underway. In August 2022, SNCF announced that it had exercised an option for 15 additional quad-current TGV M trainsets for international services valued at €590m.[3][4]
The TGV M is expected to enter service with the French train operator SNCF in TGV service in 2025;[5] deliveries will continue into the 2030s. In 2023, SNCF labelled the train as TGV InOui 2025.[5]
