 to break speed records between 250–300 kilometre per hour.

The experimental train was part of a vast research program on high rail speeds. This program covered all technical aspects, principally traction, the behaviour of the vehicles, braking, aerodynamics and signalling. Originally, two trains were to be built, but only one was produced. The second was to be a tilting train

A tilting train is a train that has a mechanism enabling increased speed on regular rail tracks. As a train rounds a curve at speed, objects inside the train experience centrifugal force. This can cause packages to slide about or seated passengers to feel squashed by the outboard armrest due to...

Each axle
Axle
An axle is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to its surroundings, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle...

The TGV 001 was an articulated train; each carriage shared one bogie
Bogie
A bogie is a wheeled wagon or trolley. In mechanics terms, a bogie is a chassis or framework carrying wheels, attached to a vehicle. It can be fixed in place, as on a cargo truck, mounted on a swivel, as on a railway carriage/car or locomotive, or sprung as in the suspension of a caterpillar...

 with the next. This setup ensured greater stability and permitted the suspension to be placed near the centre of gravity of each carriage, thus reducing rolling in curves.

History

TGV 001 was finished on 24 March 1972 and began to undergo testing on 4 April 1972. It went on to carry out 5227 test runs, running half a million kilometres and breaking the 300 kilometres per hour barrier 175 times.
