In brief
The AGV was designed before the 2008 financial crisis, when the high-speed rail market was expanding. With market demands for trains covering over 1,000 km in under three hours, speeds of 360 km/h were envisioned. However, Alstom’s AGV no longer suited the SNCF, which preferred high-capacity TGV-Duplex and 2N2 models to increase seating without adding trains and incurring extra rail tolls.
The AGV had been part of a joint bid by Alstom and CAF for the Madrid-Barcelona line, but the contract went to Talgo and Siemens. Siemens’ argument for maximizing seating capacity influenced Alstom’s design, which retained the articulated TGV architecture. The first prototype, Elisa, emerged in 2001, followed by Pégase.
Unexpectedly, the AGV’s first customer was Italy’s private operator NTV, founded in 2006. Initially considering Siemens’s ICE, NTV’s CEO discovered Pégase at Alstom’s La Rochelle facility in 2007. In January 2008, NTV ordered 25 ETR 575 trainsets, delivered between 2011 and 2012, with a 30-year, €1.5 billion maintenance contract in Nola, near Naples.
NTV’s AGV featured 11 articulated cars, 200 meters long, with a 410-ton weight. It had 10 permanent magnet motors (7,500 kW) and could reach 300 km/h, or 360 km/h with additional powered bogies. The interior, optimized for space, included Club, Prima, and Smart “atmospheres,” seating 450 passengers.
The first train was delivered in 2010, entering service as NTV-Italo in April 2012. While Alstom’s AGV future remains uncertain, NTV later ordered eight Pendolino trains in 2015.

The definition of a high-speed train varies by region, but generally, it refers to trains that operate at speeds of at least 250 km/h (155 mph) on newly built lines and 200 km/h (124 mph) on upgraded lines. In Europe, for example, the UIC (International Union of Railways) considers a commercial speed of 250 km/h as the principal criterion for high-speed rail. In the United States, the definition can include trains operating at speeds ranging from 180 km/h (110 mph) to 240 km/h (150 mph).

Background and development
The story goes that the future CEO of NTV, Giuseppe Sciarrone, arrived at Alstom La Rochelle one fine day in March 2007 for information, and discovered the Pegasus prototype in the workshop, still in the skeleton stage. He was shown the development of the AGV, an ‘Automotrice à Grande Vitesse‘.
On 17 January 2008, before the official presentation by Alstom, which took place in February, NTV-Italo placed an order with Alstom for the construction of 25 trainsets built at the La Rochelle and Savigliano plants, a plant bought by Alstom in 2000 from Fiat Ferroviaria. The contract, worth €650 million, also included maintenance of the trains for a period of 30 years, although this was not included in the price. It also included an option for 10 additional trainsets. In NTV, Alstom found its first customer to launch its new product.
Giuseppe Sciarrone was proud to state that year that “the great innovation of the introduction of competition on the high-speed networks and the challenge of a new train is now close to becoming a reality. NTV is leading the way and, for once, we can say that Italy is the leader of a major innovation process“. On 5 February 2008, the first trainset was officially unveiled at Alstom Transport’s La Rochelle plant.
Technical details
The AGV is the exact opposite of the SNCF’s preference: distributed motorisation and a single deck. It’s a genuine in-house product. Back in 2003, Alstom decided to anticipate market needs by launching a generation of very high-speed trains for customers other than the SNCF. The design of this AGV naturally drew on the French champion’s 30 years’ experience in very high speed, while opting here for financing from its own resources, without any specific customer specifications. Compatible with interoperability standards, the AGV was clearly aimed at international markets before the 2008 crisis hit…
NTV chose an 11-car articulated trainset, 200m long and weighing 410 tonnes. Distributed motorisation had been the subject of extensive research during tests with the Elisa and Pégase prototypes. The voltages selected were 25kV AC and 3kV DC. The 10 permanent magnet synchronous motors supply 7,500kW spread over five bogies. These motors have the same weight as the induction motors, but deliver much greater power.
Maximum speed is set at 300km/h with five motorised bogies, but can rise to 360km/h with six motorised bogies. Compared with the TGV, the height of the roof has been increased in order to increase the height of the interior space and accommodate equipment such as air conditioning units and braking resistors on the roof. Inside the train, the ceiling-mounted air conditioning system has freed up a few centimetres on the sides, giving an internal width of 2,750mm.
17 of the 25 trainsets were built in La Rochelle, the first of which was delivered at the end of 2010 and the second in May 2011. The last eight were manufactured in Savigliano, Alstom’s Italian plant. A test campaign led to the issue of an operating certificate in Italy. In October 2011, an NTV trainset carried out a series of tests on the Rhine-Rhone LGV, which is not yet open to service.
On-board comfort: NTV-Italo’s choices
For its on-board services, NTV has adopted the multi-class concept already in vogue at Trenitalia and Renfe. In reality, there are no classes, but rather “ambiences” in line with the marketing spirit. The trains offer a Club carriage with just 19 seats (including two 4-seater lounges), four Prima carriages with a total of 143 cosy seats, six Smart carriages with 288 seats in 2+2 seating, the last of which is a Smart Cinéma carriage with 39 seats and eight high-definition screens. All in all, 450 seats spread over eleven cars, two of which have a driver’s cab at the ends, making the AGV a ‘high-speed self-propelled vehicle’.
Launch
The NTV AGV finally entered commercial service in Italy on 28 April 2012, operating under the name ‘Italo’. On 30 March 2013, the entire fleet of 25 ETR 575 trainsets was made available. The maintenance contract with Alstom at the Nola depot provides for the permanent availability of 21 of the 25 trainsets. 🟧
