The SNCF's largest order to date were the “Autorail à grande capacité” multiple units. The goal was to replace the previously locomotive-hauled TER trains in regional traffic. They are offered for diesel and electric traction, with the B 81500 and B 82500 combining both types of power. They can run sections with overhead lines electrically with an output of 1,900 kW, while two diesel engines with a total of 1,324 kW are used for non-electrified sections. While the B 81500 is only designed for 1,500 volts direct current and consists of three or four cars, the three-car B 82500 can also be used under 25,000 volts alternating current. All variants have a powered bogie at each end and Jakobs bogies between the cars.
