Who invented TGV?

TGV (Train à Grande Vitesse, or "high-speed train") was not invented by a single individual, but rather developed through the collaborative efforts of a team of engineers and researchers at the French national railway company, SNCF. The TGV project was initiated in the early 1970s, with the goal of developing a high-speed rail system that could reach speeds of over 200 kilometers per hour (124 mph).

The TGV project was led by a group of engineers and researchers at SNCF, including:

* Roger Thevenot: Thevenot was the project director and chief engineer for the TGV, and is considered the "father of the TGV".

* Jacques Dupuy: Dupuy was the head of research and development for the TGV project.

* André Coudert: Coudert was a mechanical engineer who played a key role in the design and development of the TGV's high-speed bogies.

* Alain Barret: Barret was an aerodynamicist who worked on the design of the TGV's streamlined shape.

The TGV project was also supported by the French government, which provided funding and political backing for the development of the high-speed rail system.

The first TGV train was built in 1972 and underwent a series of tests and trials before entering commercial service in 1981. The TGV quickly became a success, and has since been adopted by other countries around the world. Today, the TGV is one of the most advanced and efficient high-speed rail systems in the world.
