World's fastest train -TGV
Monday, November 05, 2007
If you have been to Europe then its imperitive to ride TGV. TGV (train à grande vitesse, French for "high-speed train") is France's high-speed rail service developed by private major Alstom (also developed Delhi Metro) and SNCF, the French national rail operator. First established between Paris and Lyon in 1981, the TGV network runs across France and adjacent countries. TGVs link with Switzerland through the French network, with Belgium, Germany and the Netherlands through the Thalys network, and the Eurostar network links France and Belgium with the United Kingdom; where Thalys and Eurostar are fast speed trains developed by other countries.
Lets talk about speed now, how fast have you traveled in trains? Indian trains run at maximum speed of 160Kmph. On 3 April 2007 a modified TGV train reached 574.8 km/h (357.2 mph) under test conditions. The voltage on the test track between Paris and Strasbourg was boosted to 31,000 volts and extra ballast was tamped onto the right-of-way. By doing so, it beat the 1990 world speed record of 515.3 km/h (320.2 mph), set by a similarly shortened train (two power cars and three passenger cars).
TGV already runs at 320 kmph, and in case you have traveled by it, you would have already realised the effect its acceleration has on your ears as soon as it passes through the tunnels. See the video here -
