The Autorail à Grande Capacité (literally, high-capacity railcar) or AGC is a category of multiple unit train built at Bombardier Transportation's plant in Crespin for the French rail operator SNCF. Depending on the variants, the train is electric, diesel or dual-mode.

This train (first operated in 2004) has been requested by the region, has been acquired by SNCF in 700 units. Because of this modularity, each region has chosen the cars number (from 2 to 4 in theory, but 3 or 4 in reality) and the interior design (first class, bar area, ski racks, etc.) for their fleet.

The company Remarul 16 Februarie has signed a contract with Bombardier in November 2020, for purchase of license for manufacturing AGC in Romania at Cluj-Napoca. Under the contract, Remarul will exclusively manufacture and sell this train in six countries: Romania, Bulgaria, Greece, Croatia, Bosnia and Serbia.

All the French regions acquired an AGC Class (all variants together). The AGC Class fleet is the most important in 2010. By the fact, with this huge numbers of units in operations, AGC is well implanted in all regions since the 2000s.
