In 2007, Provence-Alpes-Côte d'Azur awarded the supply of 4 AM 800 diesel, metric gauge trains. These units are made up of 2 cars each, with each car including a motor bogie and a trailer bogie, covering the route between Nice and Digne. It is estimated that these new trains will help to increase passenger capacity on this route by 60%. The trains were delivered in 2010.
