The AGV (acronym for French: Automotrice à grande vitesse) is a standard gauge, high-speed, electric multiple-unit train, designed and built by Alstom.
Alstom offers the AGV in configurations from seven to fourteen carriages, seating 245 to 446 persons. The trains are constructed from units comprising three cars (each with one transformer and two traction electronics packages located underneath the cars) and single-car driver-trailers. The maximum commercial speed is 360 km/h (220 mph).
Design of the train took place through the early 2000s, with a prototype, "Pegase", produced in 2008. As of 2016, the only commercial order for the train has been from Italian transport company NTV, which ordered 25 trains in 2008, beginning services in 2012.
According to Alstom, the advantages of the AGV are: increased seating area per train length (compared to a single-deck TGV); safety and maintenance advantages of the Jacobs bogie articulation design; as well as higher energy efficiency from permanent-magnet synchronous motors.
The first design studies relating to the AGV were made in 1998. An AGV design, initially named "TGV 400" was presented in Barcelona in early 2000 as part of Alstom's bid to supply high-speed trains for the Madrid–Barcelona high-speed rail line. Initial specifications were for a train with distributed traction (total power 7.2 MW), seating 359 in a train 180 metres long, with a version including eddy current brakes with a top speed of 350 km/h (220 mph), and a tilting version with a top speed of 320 km/h (200 mph). The design would retain the articulated Jacobs bogie of the TGV.
Unlike the TGV, which was developed in collaboration between Alstom and SNCF, the AGV was developed wholly at Alstom's expense, with European Union rules on state aid limiting the extent of financial collaboration between the state-owned SNCF and Alstom. The AGV was promoted in 2002 as a complementary high-speed train to the TGV Duplex, offering higher speeds for less busy train paths, while a double-decker AGV was posited as a future possibility by Alstom.
