caption_attribution_description: English: CRH2-139E, which was destroyed in the Wenzhou accident in July 2011.
context_page_description: The Wenzhou train collision occurred on 23 July 2011 when two high-speed trains travelling on the Yongtaiwen railway line collided on a viaduct in the suburbs of Wenzhou, Zhejiang province, People's Republic of China. The two trains derailed each other, and four cars fell off the viaduct. 40 people were killed, at least 192 were injured, 12 of which were severe injuries. This serious traffic disaster was caused by both the critical defects of design and the rough management of the bullet train company. Officials responded to the accident by hastily concluding rescue operations and ordering the burial of the derailed cars. These actions elicited strong criticism from Chinese media and online communities. In response, the government issued directives to restrict media coverage, which was met with limited compliance, even on state-owned networks.
  The collision is the only fatal crash involving high-speed rail in China, and is the third-deadliest HSR accident in history, after the 1998 Eschede derailment in Germany and 2013 Santiago de Compostela derailment in Spain.
context_section_description: The two trains involved were based on technology from Bombardier and Kawasaki. Train  CRH1-046B is a variant of the Swedish Bombardier Regina, while the second train CRH2-139E is a derivative of the Japanese E2 Series Shinkansen 'bullet train.' Kawasaki and other companies in Japan are currently challenging China's high-speed rail project for patent license violations. The Chinese maker has been attempting to patent the same technology and alleged improvements. The trains were of the "D train" class and thus in the first generation of China's express trains, not the faster "G train" class, which travel at more than 300 km/h (186 mph).
