The french TGV (train à grande vitesse, High speed train) sets a new conventional rail record, with a speed of 574.8 kmh. The record was established on April 3,2007, surpassing the previous record of 1990 (515.3kmh). The train is a special tgv, named "V150" (for 150 met/sec, ca. 540kmh)with a souded-up engine (25,000hp, like two F1 starting grids), and larger wheels. This is a test run, in order to make the train able to run at a 360+ kph in commercial services. Coverage of the final sequence is provided by a plane. The speedmeter show a speed computed via GPS, explaining the difference (0.1kph) with the actual speed.
Technology is based on research from all around the world: UK, with the first railways, Japan, who created the first HSL, Italy who imported it in Europe. France with the TGV, Germany with the ICE. This train being actually an "hybrid" of French and German tech. Today China enters the big game, perfecting tech from Germany. Argentina, Morocco, and Saudi Arabia are currently planning several high speed line. The US might have a HSL in the next decade.
And don't forget those machines runs on AC, thanks to the Serbian-American Nikola Tesla. And finally, thanks to that Sumerian guy who invented the wheel, thousands of years ago. Keep in mind that we all stand "on the shoulder of giants". Whatever our nationality is, technology and science is ultimately shared between us all.
Le TGV atteint la vitesse de 574.8 kmh, établissant un nouveau record du monde de vitesse sur rail. Le record est établi le 3 avril 2007, surpassant le précédent record de 1990 (515.3kmh). Le train est un tgv spécial, avec des moteurs survitaminés (25,000 cv, l'équivalent de deux grilles de départ de F1), des roues plus larges...
