SNCF Class T 2000 SNCF Class T 2000 SNCF Class T 2000 trainsets, also known under their French acronym RTG ("Rame à turbine à gaz," i.e., gas turbine trainset), were the second generation of turbine-powered trains in France and saw commercial service from 1972 to 2004. Building on the successful experience of the earlier TGS and the ETG turbotrains, French state railway company SNCF commissioned the T 2000 for entry into service in the early 1970s. The objective was to offer the same service speed as electric traction ( at the time) on French trunk lines that had yet to be electrified. The first
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.
