According to HK meida, at least two cars off the bridge. At least 11 killed. The final number will be a lot higher.

Report I read is that southbound D3115 from Hangzhou to Wenzhou stopped after being a lightning strike. The Beijing-Fuzhou D301 following plowed into the stopped train.

I'll look up the schedule in a few minutes to see how far the trains are supposed to be apart.

Running highspeed or semi-highspeed trains the Japanese and Chinese do - with just a few minutes apart on some routes - require redundant safety systems when it comes to signaling issues. Took the Japanese years to get to run the few-minutes-apart schedule on their Shinkansen in an earthquake-prone area. What kind of experience and backup systems do the Chinese put on their track?

Edit: Looking at the schedule, D3115 is Hangzhou to Fuzhou South, D301 is Beijing to Fuzhou South. But D301 is supposed to be about 15 minutes ahead of D3115, arriving at Wenzhou South 19:42 vs 19:57. Perhaps D301 was late, or the media has one or both of the train numbers wrong.
