The Alstom Avelia Euroduplex, more commonly known as just Euroduplex, is a high-speed double decker electric multiple unit train manufactured by Alstom. It is primarily operated by the French national railway company SNCF, and also in operation with the Moroccan national railway company ONCF. It is the 3rd generation of the TGV Duplex.
The Euroduplex trains are interoperable, containing equipment allowing them to travel between several european continental countries with various types of electrification and signalling systems such as France, Germany, Switzerland, Spain and Luxembourg. A Moroccan variation will be the first high speed train to operate in Africa.
The Euroduplex trains are an evolution of the TGV Duplex Dasye and still share the main features. The drive is of type TGV POS asynchronous traction motors, European signaling system European Rail Traffic Management System. The trailers feature new interiors, electric sockets fitted in both classes and improved information systems.
The main differences with the TGV Duplex Dasye:
- UIC loading gauge with more headroom upstairs
- Improved windows
- Passenger Information System (SIVE) with voice announcements as in the TER trains.
- Outside SIVE dynamic light display indicating the number of the train, its route and the number of the car
- Fixed filler gaps on all doors,
- Control over the train hot boxes (two sensors per box for redundancy)
- Overall control of each axle
- Improved accessibility for wheelchairs
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 (only 8 trains TGV Sud-Est could operate at this current and 19 trains are then TGV POS), the train is a tricurrent version of TGV Duplex.
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.
In June 2007, in addition to 25 extra TGV Dasye sets (+ 3 others 2008), 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" (tricurrent Germany), numbered 4701-4730 (4 international) 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" (tricurrent Spain), numbered 801 to 810, for services between France and Spain (deliveries from 2013);
- 15 trains "3UF" (tricurrent France), numbered 811-825, intended for domestic traffic in France (deliveries from 2014);
- 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.
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 sets will then have 95 cars. These trains will be able to replace some sets on TGV Atlantique or even LGV Est services in 2016.
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 320 km/h (199 mph) on the section Tangiers — Kenitra and between 160–220 km/h (99–137 mph) 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 (due to land acquisition difficulties), Alstom Transport incurs additional costs, in particular through the forced storage of several trains in its factories. The first dynamic tests of a train (No. 1201, specially assigned to tests) began in January 2016, on the classic line connecting Tangier to Casablanca, with drivers who were specially trained (partly in France, by the SNCF ); these tests were completed in July 2016. At the same time (on 11 July), 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 (which constitutes the record of rail speed in Africa).
The maintenance center, with a total capacity of 30 trains and an area of 14 hectares, is located in Tangier-Moghogha. It is operated in partnership with SNCF, within the framework of the joint venture "Moroccan high-speed train maintenance company".
Since its introduction into commercial service, the 4700 numbered trains operate priority international services:
- Alleo Paris-Est — Stuttgart — Munich (via LGV East Europe)
- Alleo Frankfurt — Strasbourg — Lyon-Part-Dieu — Marseille (via the LGV Rhin-Rhône and Mediterranean)
- Lyria Paris-Gare de Lyon — Basel — Zürich (via the Rhine-Rhône) since January 2012 (three of the six round trips, the others being operated by TGV POS)
The 800 numbered trains are designed to provide international services to Spain:
- Elipsos: Paris-Gare de Lyon — Lyon Part Dieu — Montpellier — Figueres — Barcelona (in a pool with TGV Duplex Dasye)
