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.
