(SHAGHAI) -- A collision between two subway trains in Shanghai Tuesday has left more than 200 people injured -- about twenty seriously -- according to the subway operator.
Shanghai Shentong Metro Group Co. said on its Weibo account -- a Chinese social media website much like Twitter -- that the crash occurred at 2:51 p.m. on Line 10. The company said a signal system failure caused one train to accidentally rear-end another.
Nearly 500 passengers who were on the trains have been safely evacuated, Shanghai Metro added.
