on 5 june 2000, 373101/102 on a paris to london service derailed on lgv nord near arras, france at 180 mph (290 km/h). 14 people were treated for light injuries or shock, with no serious injures or fatalities. the articulated design was credited with maintaining stability during the incident and the train stayed upright. after investigation, the incident was blamed on a component of the transmission between the motors and axles coming loose. to reduce the unsprung mass, tgv trains have the motors attached to the train rather than the bogies. in order for the train to be able to go around curves a sliding "tripod" assembly is used, which became dislodged.
