Derailment
A refurbished 200 series train (set K25 on the Toki 325 service) derailed on the Jōetsu Shinkansen line while travelling at a speed of approximately 200 km/h between Nagaoka Station and Urasa Station on 23 October 2004 during the 2004 Chūetsu earthquake. Eight of the ten cars were derailed. This was the first derailment of a Shinkansen train in service. None of the 155 passengers on board was injured. Set K25 was officially withdrawn on 25 March 2005.
