The TGV POS is a French TGV train currently under testing for use on the LGV Est. POS stands for Paris-Ostfrankreich-Süddeutschland (Paris, Eastern France, Southern Germany). For the group of heart conditions referred to as TGV, see transposition of the great vessels. ... The LGV Est européenne (sometimes referred to as TGV Est, or occasionally as TGV East in English) is an extension to the French high-speed TGV network, connecting Paris and Strasbourg. ...

Each train will be formed from 8 existing TGV Réseau single-deck carriages, which will be paired with new power cars, giving a total power output of 9,600 kW (12,900 hp) and a top speed of 320 km/h (200 mph) under 25 kV. The TGV Réseau power cars thus freed will be matched with new TGV Duplex carriages to create TGV Duplex - TGV Réseau hybrid sets. This is because traffic on the LGV Est is expected to be less than on the heavily congested LGV Sud-Est and LGV Nord. The SNCF TGV Réseau (TGV-R) trains were built by Alsthom between 1992-1996. ... The kilowatt (symbol: kW) is a unit for measuring power, equal to one thousand watts. ... hp, see HP (disambiguation). ... The TGV Duplex is a French high-speed train of the TGV family. ... The LGV Sud-Est is a high-speed railway line running between Paris and Lyon, in France. ... The LGV Nord is a French 333 km-long high speed rail line that connects Paris to the Belgian border and the Channel Tunnel via Lille; it opened in 1993. ...

Unlike the TGV Atlantique (but like the Class 373 Eurostar) the TGV Réseau and the TGV Duplex have asynchronous motors and, in case of failure, isolation of an individual motor in a powered bogie is possible. By using IGBT power packs, the new power cars are capable of developing 75% of their full rated power under 15 kV German electrification, compared to just 45% for existing TGV power cars. This will allow POS trains to operate at the same speed as InterCityExpress trains in Germany. TGV-A set 359 at Poitiers Futuroscope on 28 August 2001. ...

Each TGV POS trainset weighs 423 tonnes (466 short tons; 416 long tons) and is numbered in the 4400 series. The short ton is a unit of mass equal to 2000 lb (exactly 907. ... Long Ton (sometimes known as a Gross Ton, Weight Ton, or Imperial Ton) is the name for the unit called the Ton in the Avoirdupois or Imperial system of measurements, as formerly used in the United Kingdom and several other Commonwealth countries. ...

World rail speed record

Main article: TGV world speed record

TGV POS trainset number 4402 set a new world speed record (for travel on conventional rails) on April 3, 2007. The train reached 574.8 km/h (357.2 mph).^[1] As part of a series of increasingly faster runs that culminated in the official record attempt, it set an unofficial speed record of 554.3 km/h (344.42 mph) on February 13, 2007. The trainset comprised three specially modified Duplex cars, fitted with two powered bogies similar to the AGV prototype, marshalled between the TGV POS power cars. The trainset had four more powered axles than trainset 325 in the 1990 speed record, and had a theoretical maximum power output of 19.6 MW (26,820 hp) instead of the 9.3 MW on a standard TGV. Over 600 sensors were fitted on various parts of both the engines and the cars. The train set ran with larger wheels, and the catenary voltage was increased to 31 kV from the standard 25 kV.^{[2] [3]} The peak speeds were achieved near kilometer post 193 on the LGV Est, between the Meuse and Champagne-Ardenne TGV stations. This section of the track itself is a down-hill stretch. The TGV world speed record program was a series of trials by SNCF, the French national railway to test its TGV system to the limits. ...
