TGV 001 , experimental Turbotrain brought into service in 1972, was built by Alsthom and was conceived in collaboration with the SNCF to explore the beach speeds ranging between 250 and 300 km/h from the point of view of the creation of a network of lines at high speed.

In the beginning, two oars were to be built, but only one was born. The second was to be a pendular version equipped with a system of pendulation activates, but it was abandoned vis-a-vis technical difficulties of realization.

Description

This turbotrain, of design completely different from those which preceded it (ETG, RTG), was made of an oar with total adhesion (all driving axles) made up of two driving S and three intermediate trailers.

Its technical design (except for the motorization by gas turbines) and its new esthetics with its aerodynamic forms were taken again for the oars TGV of series which were brought into service starting from 1981.

All the Essieu X were equipped with Moteur S electric, with the advantage of a weak load to the axle and a high specific power.

The electric traction allowed also dynamic braking, particularly effective at high speed. Each motor coach was equipped with two turbines (TURMO III G then TURMO X, also equipping the helicopters Super Frelons with Southern Aviation) which turned at constant speed. They ordered a speed-reduction gear involving a Alternateur. In addition to the ordering of the turbines, the motor coaches were equipped with the controlling system of the engines of traction, the indication and the equipment of braking, etc

The TGV 001 was an articulated oar, the adjacent cases resting on a common Bogie. This provision gave him a greater stability (by the dynamic coupling of the two cases) and left the place to a second stage of pneumatic suspension placed at the level of the Center of gravity, thus reducing rolling in the curves.

Service

This oar, which held the railway world speed records in thermal traction a long time (318 km/h), forever used in business service.

It belonged to a research vast program on railway high speeds, recovering all the technical sides, in particular traction, the dynamic behavior of the vehicles, the old Frein, the Aérodynamique, the indication.

Other features

• Composition of the oar (five vehicles)
• 2 identical motor coaches: TDu-001 and TDu-002
• 3 trailers: TRAu-20701 (arranged in 1st class), TRAu-500001 (car laboratory), TRBu-30701 (arranged in 2nd class)
• Motorization:
• each motor coach is equipped with two turbines Turmo III G (derivative of those equipping RTG); the generator includes/understands two alternators, the main thing and auxiliary;
• electric drive into three-phase current-continuous;
• driving of traction: two engines per axle;
• Braking: the oar has four type of brakes:
• rheostatic Brake (driving);
• brake with eddy currents (gone up on the end of the driving shafts), it is the basic brake;
• magnetic brake (shoes supporting on the Rail), it is emergency braking;
• expanding brake with oil and air order (shoes with sole of cast iron pressing on a side of the Wheel S), it is the braking of stop.
• the oar is air-conditioned.

History

The TGV 001, left factory the March 24th 1972, begins its tests in line April 4th of the same year. It will carry out 5227 trial runs, traversing on the whole nearly a half-million kilometers and exceeding 175 times the speed of 300 km/h.

The December 8th 1972, during a trial run on the line of the Moors, the TGV 001 reached the speed of 318 km/h, world records speed for a train with thermal traction.

The tests officially ceased the June 19th 1978.

Preserved motor coaches (2005)

• T 001: Bischheim (the Low-Rhine),
• T 002: Belfort (Territory of Belfort).

These two motor coaches are exposed at the edge of the exits of highways leading to the workshops of maintenance of these two cities.
