Operation V150, where 150 refers to a target speed in metres per second, was a series of high-speed trials carried out on the LGV Est. The V150 was a specially configured TGV high-speed train (weighing only 265 tonnes (292 tons)) notable for breaking the world railway speed record on 3 April 2007. The train was built in France and reached a speed of 574.8 kilometres per hour (357.2 mph) on an unopened section of the LGV Est between Strasbourg and Paris, in France[1] topping the previous record of 515.3 kilometres per hour (320.2 mph) set in 1990.[2]
