This number increases rapidly with certain widespread technologies: 2 bearings are added for the air-conditioning compressor, for example. Regarding shafts, there are 6 units on an entire transmission system (2 main bearings on the longitudinal shaft, 4 bearing in the rear differential). For the engine, 2 bearings are regularly seen at the end of the cam shaft (distribution end).

The list is not exhaustive: bearings are also sometimes found in surprising locations, such as in Citroën’s fixed-centre steering wheel.

It is operated in partnership with SNCF, within the framework of the joint venture "Moroccan high-speed train maintenance company".[citation needed]
The Euroduplex trains are interoperable, containing equipment allowing them to travel between several European continental countries with various types of electrification and signalling systems. A Moroccan variation is the first high-speed train to operate in Africa.
Since 26 November 2018, the Moroccan trains make the connections between Tanger and Casablanca via Rabat.[20] The name of the commercial service is Al Boraq.[21]

In December 2010, the Moroccan company ONCF ordered 14 sets of the Euroduplex for Kenitra–Tangier high-speed rail line.[13] The contract of €400 million expected commissioning in 2015.[14] The ordered trains are electrified at 25 kV and 3 kV and can operate up to 320 km/h (200 mph) on the section Tangiers — Kenitra and between 160–220 km/h (99–137 mph) on the Moroccan conventional network.
To save the workforce of the Alstom factory in Belfort, the French government announced in October 2016 the purchase of fifteen trains to be used on the intercity line between Bordeaux and Marseille. SNCF carried out the order in February 2017. These trains, of the 3UFC type, are numbered from 836 to 850 and have been delivered since August 2019.[citation needed]

In June 2007,[8] 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.
The 3UFC are all operating from Paris Montparnasse firstly towards Bordeaux — Agen — Montauban — Toulouse — Arcachon — Dax — Bayonne — Biarritz — Saint-Jean-de-Luz — Saint-Jean-de-Luz — Pau — Lourdes — Tarbes. Then towards Le Mans — Rennes — Quimper — Brest — Angers — Nantes — Saint-Nazaire — Le Croisic — Les Sables-d'Olonne. Since 2021 some trains started operations from Paris Lyon towards Lyon, Saint-Étienne, Marseille and Nice.

The trains are used on domestic routes (via the LGV Est to Strasbourg, Reims, Remiremont, but also via the Rhin-Rhône to Colmar and Mulhouse among others).
Avelia Euroduplex, more commonly known simply as Euroduplex or TGV 2N2 in France, is a high-speed double-decker train manufactured by Alstom.[4][5] It is primarily operated by the French national railway company SNCF, and also in operation with the Moroccan national railway company ONCF.[5] It is the 3rd generation of the TGV Duplex.

In April 2010, the first train RGV, numbered 4701, was tested at La Rochelle.[9] 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.
Riding on the success of the concept TGV Duplex, and praised by customers[citation needed], 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.[citation needed]

The 2007 contract included an option for 40 additional trains. SNCF exercised this option[11] to take delivery of the second batch of Euroduplex sets from 2015. These are the 3UFC type (the "C" stands for capacity) and named "Océane". They 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 interior design and a capacity expanded by 10% mainly due to the third car being multi-class, and were delivered between 2016 and 2019 and are numbered from 851 to 891 (minus 866, which only consists of power reserve motors).

The Euroduplex trains are an evolution of the TGV Duplex Dasye and still share the main features.[citation needed] The drive is of type SNCF TGV POS asynchronous traction motors, European signaling system European Rail Traffic Management System.[citation needed] The trailers feature improved information systems and the 3UFC type feature new interiors with rotating seats and USB sockets.

The Moroccan trainsets have a total capacity of 533 passengers in two first-class carriages, five second class carriages, and a catering coach,[15] instead of the French configuration of three first class coaches, four second-class coaches, and a catering coach.[citation needed] The modifications were made according to the Moroccan climatic and environmental conditions.[16] The first two cars will be delivered during the summer of 2015[needs update], transported from the port of La Rochelle by the ship Ville de Bordeaux.[citation needed] 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.[citation needed] 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.[citation needed] At the same time (on 11 July), the twelve trains were delivered. LGV testing began in February 2017 and was completed in June 2018; during one of them, carried out on 4 May 2018, the train achieved a speed of 357 km/h (220 mph) (which constitutes the record of rail speed in Africa).[citation needed] During this period, Alstom delivered 12 trains for the Tangier-Casablanca railway section.[17] King Mohammed VI and French President Emmanuel Macron participated in the inauguration.[17] Upon launch, it became the first high-speed railway line in Africa.[18]
This obviously depends on the model! We’ve nevertheless undertaken to give a rough count of the minimum number of bearings in a car. We counted 36.
The sophistication of certain functions tends to drive up the number of bearings. Recent automatic dual-clutch transmissions (DCT) require an additional 3 bearings: 2 on the gearbox’s second primary shaft, and 1 for the double clutch. Certain high-end engines feature one bearing per valve, i.e. 4 per cylinder and thus 48 on a 12-cylinder engine!

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.[citation needed]
In July 2019, SNCF announced an order of twelve trains that would be delivered between 2021 and 2023 (shortly before the arrival of the first Avelia Horizon) with the last trainset being delivered in april 2023.[12] The complete fleet would consist of 122 trains.
Since its introduction into commercial service, the 4700 numbered trains operate priority international services:[citation needed]
