SNCF TGV POS SNCF TGV POS The TGV POS is a TGV train built by French manufacturer Alstom which is operated by the French national rail company, the SNCF, in France's high-speed rail lines. It was originally ordered by the SNCF for use on the new LGV Est, which was put into service in 2007. "POS" stands for "Paris-Ostfrankreich-Süddeutschland" (German for "Paris, Eastern France, Southern Germany"). Each train is formed of eight existing TGV Réseau single-deck carriages paired with new power cars, with a total power output of and a top speed of under 25 kV. The TGV Réseau power cars thus freed
SNCF Class BB 15000 with the BB7200 and BB22200 series and have even a great deal in common with cabs of other SNCF locomotives of the 1960s. This class was also the first to introduce the VI ("Vitesse Imposée") cruise control system which is now standard on all SNCF locomotives delivered after 1971. The electrical part consists of a single pantograph (type AM18U) which collects 25 kV from the catenary. Power is passed through a transformer which lowers the tension to about 1500 V AC and a bridge rectifier controlled by thyristors rectify it into DC, which is then fed into the traction motors.
