Leaks from the official investigation into the high-speed train crash at Wenzhou that killed 40 on July 23rd suggest that lightening and mismanagement are being fingered for the blame (here via Caijing). What is being described as lightening that flashed 100 times in seven minutes is believed to have stalled the first train while a faulty signal failed to stop the second train running into it from behind. While there have been reports of systemic problems with the sensors in the signaling system, the lightening strikes may have knocked this particular one out.
As we have noted before, lightening is a deadly killer in China. Some 300 people were killed by it last year, and in 2007, 744 died from lightening strikes.
