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.

History

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 (160 km/h or 99 mph at the time) on French trunk lines that had yet to be electrified.

The first trains were put into service in late 1972 on the Lyon-Strasbourg and Nantes-Bordeaux routes, two key trunk lines that were not electrified at the time. Though the trainsets were rated for 160 km/h (99 mph), they only could achieve this speed on short sections due to the ancient design of the lines (particularly on the Nantes-Bordeaux route) that restricted speed to 120 km/h (75 mph) on many segments. As the capacity of the smaller T1000s serving the Western line from Paris-Saint-Lazare to Caen and Cherbourg was proving less and less adequate, the next batch of T 2000s was affected to this line whose straighter profile allowed them at last to demonstrate superb performance and reliability.
