History
Riding on the success of the concept TGV Duplex, and praised by customers, the company decided to develop a fleet of interoperable trains, especially suitable for 15 kV 16 ⅔ Hz, the train is a tricurrent version of TGV Duplex. The Euroduplex has entered commercial operation by the French national railway company on. In parallel with the development of high-speed lines internationally, Alstom SA won a tender for the supply of equipment for high-speed TGV Morocco, the first high-speed train on the African continent.
Operators
SNCF
In June 2007, in addition to 25 extra TGV Dasye sets, the SNCF has placed a large order for 55 Alstom tricurrent high speed trains, TGV 2N2. These 55 trains can be divided into:
30 trains "3UA", numbered 4701-4730 for services from France to Germany and Switzerland. Prototypes were tested from August 2010, the remaining deliveries expected between 2011 and 2014;
10 trains "3RU", numbered 801 to 810, for services between France and Spain ;
15 trains "3UF", numbered 811-825, intended for domestic traffic in France ;
A Power Reserve "3UA" compatible with the 55 cars and also for the TGV POS and TGV Duplex Dasye.
In April 2010, the first train RGV, numbered 4701, was tested at La Rochelle. On 16 June 2010, the train arrived at the site of ELWT Conflans to be equipped with different systems to perform many tests in the coming months before commercial operation. Between 20 and 30 July 2010, the train conducted speed tests in Switzerland, Germany, the Netherlands, Belgium and the French Alps. SNCF and Alstom organized the symbolic delivery of the first train on May 30, 2011 on the LGV Est. The 2007 contract included an option for 40 additional trains. SNCF exercised this option to take delivery of the second batch of Euroduplex sets from 2015. These the 3UFC type and named "l'Océane" were delivered between 2016 and 2019 and have replaced some sets on TGV Atlantique with the opening of the LGV Sud Europe Atlantique. They offer a new inerior design and a improved capacity by 10% due to the third car being multi-class and were delivered between 2016 and 2019 and are numbered from 851 to 891. To save the jobs of the Alstom factory of Belfort, the french state announced in October 2016 a order of fifteen trains to be used on the Intercity line between Bordeaux and Marseille. That order was done by the SNCF in February 2017. These trains are from the 3UFC type numbered from 836 to 850 and are in delivery starting form August 2019 and are used with the others 3UFC. Finally in July 2019, the SNCF announced the order of twelve trains that will be delivered between 2021 and 2022. The complete fleet would have 122 trains once the final order would be done.
ONCF
In December 2010, the Moroccan company ONCF ordered 14 sets of the Euroduplex for Kenitra–Tangier high-speed rail line. The contract of €400 million expected commissioning in 2015. The trains are electrified at 25 kV and 3 kV and can operate at up to on the section Tangiers — Kenitra and between on the Moroccan conventional network. The Moroccan trainsets have a total capacity of 533 passengers in two first class carriages, five second class carriages, and a catering coach, instead of the French configuration of three first class coaches, four second class coaches, and a catering coach. The first two cars will be delivered during the summer of 2015, transported from the port of La Rochelle by the ship Ville de Bordeaux. The project being more than two years late on its initial schedule, Alstom Transport incurs additional costs, in particular through the forced storage of several trains in its factories. The first dynamic tests of a train began in January 2016, on the classic line connecting Tangier to Casablanca, with drivers who were specially trained ; these tests were completed in July 2016. At the same time, the twelve trains were delivered1. LGV testing began in February 2017 and was completed in June 2018; during one of them, carried out on May 4, 2018, the train rode at 357 km/h. The maintenance center, with a total capacity of 30 trains and an area of 14 hectares, is located in Tangier-Moghogha.
