A specially modified TGV high-speed train known as Project V150, weighing only 265 tonnes, set the world record for the fastest wheeled train, reaching 574.8 km/h (357.2 mph) during a test run on 3 April 2007. In 2007, the world’s fastest scheduled rail journey was a start-to-stop average speed of 279.4 km/h (173.6 mph) between the Gare de Champagne-Ardenne and Gare de Lorraine on the LGV Est, not surpassed until the 2013 reported average of 283.7 km/h (176.3 mph) express service on the Shijiazhuang to Zhengzhou segment of China’s Shijiazhuang–Wuhan high-speed railway. During the engineering phase, the transmission voie-machine (TVM) cab-signalling technology was developed, as drivers would not be able to see signals along the track-side when trains reach full speed. It allows for a train engaging in an emergency braking to request within seconds all following trains to reduce their speed; if a driver does not react within 1.5 km (0.93 mi), the system overrides the controls and reduces the train’s speed automatically. The TVM safety mechanism enables TGVs using the same line to depart every three minutes. We celebrate this record with an AI image of the TGV at 574.8 km/h …
