There was also an abundance of diesel railcars, in particular first the ABJ, 90 hp FNC and X5500/5800 classes. Several different railcars were in service from the mid-1980s. The 300 hp X3800 series 'Picassos' ran from Bourg to Bellegarde until the 1980s and were then replaced by X2100s between la Cluse and Bellegarde. They could be found coupled to X2800 (a powerful 825 hp railcar designed to haul several carriages and operate on steep gradients). These railcars were still in service up to closure of the line. Occasionally, new generation X 73500 railcars were used to complement the X2800s.
