The TGV (Train a Grande Vitesse) is France's high- speed rail service. It started in the 1970s. Originally, it was powered by gas turbines. But in 1973, the TGV was changed into electric trains. The TGV service first started between Paris and Lyon in 1981. Later, the network connected other cities in France with Paris.A TGV test set the world record for the fastest conventional wheeled train on 3 April 2007. It reached the speed of 574.8 km/h ( 357.2 m/h ) on the test run. But the regular TGV trains operate at the highest speed of 320 km/h ( 200 m/h ). It is the present world record of speed of a conventional commercial train.
