The AGC fleet comprises:
- 163 class X 76500 three or four-car DMUs
- 185 class B 81500 three or four-car bi-mode units (1.5kV dc plus diesel)
- 140 class B 82500 four-car bi-mode, dual-voltage units (1.5kV dc/25kV ac plus diesel), and
- 211 class Z 27500 three or four-car dual-voltage EMUs.
In 2019 the manufacturer announced that it would be ready to convert all 325 bi-mode class B AGC units to battery EMUs, replacing the two diesel engines with battery packs during mid-life refurbishment.
The €38.5m conversion will be financed by French National Railways (SNCF), which is contributing€6m, Bombardier (€5.5m) and the Auvergne-Rhône-Alpes, Hauts-de-France, Nouvelle-Aquitaine, Occitanie and Provence-Alpes-Côte d’Azur regions (€5.4m each).
The converted units will be tested on the Lyon - Bourg-en-Bresse, Bordeaux to Le Verdon and Saint Mariens, Nîmes - Le Grau-du-Roi, Marseille - Aix-en-Provence and Abancourt - Beauvais - Creil lines.
The batteries, which are guaranteed for 10 years, are expected to provide power for at least 80km.
