The àgrandecapacitéAutorail 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. The train comes in three variants, electric, diesel or dual-mode.
This train was first operated in 2004. It was created at the request of the regional railways of France, and has been very successful, with SNCF acquiring over 700 units. The AGC is designed to be modular, and regions can chose to create trains of 2 to 4 cars, in theory. So far, all trains built have had 3 or 4 cars. As well, the interior design is also modular, and regions can chose to include features such as first class seating, a bar area, ski racks, and other amenities for their fleet.
The Romanian company Remarul 16 Februarie has signed a contract with Bombardier in November 2020, for the purchase of a licence for manufacturing the AGC in Romania at Cluj-Napoca. Under the contract, Remarul will exclusively manufacture this train for sale in six countries: Romania, Bulgaria, Greece, Croatia, Bosnia and Serbia.
All the French regions have acquired AGC Class trains (all variants together). The AGC Class fleet is the most important regional train in France as of 2010. By the fact, with this huge numbers of units in operations, AGC is well implanted in all regions since the 2000s.

Deliveries
The first car delivered was a B 81500, numbered B 81501, and was put into service on February 6, 2004, for TER Midi-Pyrénées service. The 200th trainset was put into service on November 20, 2006, on the TER Haute-Normandie. The first B 82500 unit was delivered in February 2007 and entered into service on the TER Champagne Ardenne on May 15, 2007.
Variants
The series consists of 4 models: X 76500: diesel variant, also designated XGC or Diesel AGC Z 27500: electric variant capable of running on both and , also designated ZGC or Electric AGC B 81500: dual-mode variant, capable of running on both diesel (by means of a diesel-electric motor) and 1,500 V DC (by means of a pantograph), also designated BGC B 82500: dual-mode variant, capable of running on both diesel (by means of a diesel-electric motor) and 1,500 V DC or 25 kV 50 Hz AC (by means of a pantograph), also designated BGC or BiBi (for dual-mode and dual-voltage); these trains are identical to the B 81500-series except for their capability of operating on 1,500 V DC power. This technology enables the B 82500 to glide seamlessly across the entire French railway network and to access electricity from any available source. This will result in energy savings and reduced greenhouse gas emissions, as well as negating infrastructure constraints and the need for passengers to change trains.
Design
General
Bombardier vehicle design is articulated using bogies between the carriages.
Performances
Depending on configuration, the trains can attain speeds of up to 160 km/h (99 mph). A two-car set diesel variant was initially proposed (with a speed limit of 140 km/h), but none of this variant was acquired by any region.
Operating
The modularity of these trains permits each railroad (or region) to choose the number of units – currently 3 or 4 – that make up the train, as well as the interior layout of the cars (e.g. lounge car, first class, etc.). Trains can also be made up of mixed units, i.e. a train can be made up from both BGC and ZGC units. Basse-Normandie and Lorraine regions have also ordered sets that consist of both diesel and electric units (i.e. XGC and ZGC). A two-unit variant has never been ordered; the B 82500 is only available in a four-unit version.
Remarkable trains
"Connected AGC" (in French : AGC Connecté) : since 2009, TER Ocitanie operates an AGC equipped with several sensors and IoT to experiment innovating services in real conditions. With a new onboard/ground communication system, all the data from the sensors and the IoT are sent in real time. On the ground, the collected data are analysed (temperature in the train, water level of the toilets, batteries information, etc.) in order to plan a maintenance operation before the train can be forwarded into a Technicentre(French maintenance Workshop). In the future, these data will be used to create high-performant algorithms to elaborate a predictive maintenance (CBM). This project was developed by SNCF and loT Valley (an association composed of several start-ups specialized on the IoT).
