中国总理温家宝星期四保证对中国2008年以来造成死亡人数最多的铁路事故进行全面和公开的调查，并表示被发现有问题的任何人都将受到严厉处罚。温家宝星期四视察铁路事故现场时还说，政府的当务之急是保护人民的生命。这次铁路事故造成39人死亡，将近200人受伤。
中 国铁路官员星期四说，这次事故是信号设备的严重设计缺陷造成的，一列高速火车在上海以南遭到雷击停驶后，信号没有从绿色变为红色，导致第二列火车撞到第一 列火车的尾部，几节车厢从一座桥上坠落。铁路官员还说，中国制造的信号设备失灵后，温州一个车站的调度员本应以手动操作方式进行干预。
Chinese Premier Wen Jiabao promised Thursday a complete and open investigation into the nation's deadliest train accident since 2008, saying anyone found to have been at fault will be punished severely.Mr. Wen also said the government's top priority is to protect peoples' lives during a visit Thursday to the site of Saturday's train wreck, which killed 39 people and injured almost 200.
Earlier Thursday, railway officials said the crash was caused by a severe flaw in the design of signaling equipment which prevented a green light from turning to red after a lightning strike halted a train on a high-speed line south of Shanghai. That caused a second train to smash into the rear of the first, toppling several carriages off of a bridge.The officials also said dispatchers at a station in Wenzhou should have intervened manually after the Chinese-made signaling equipment failed.
