Terrible news to hear. Wonder if China has a NTSB like entity that will do a public review of the accident. Safety is clearly a concern with HSR but even the slow stuff in the US has problems.

Yesterday afternoon, Amtrak suspended all traffic between Boston and NY. Apparently a truck ran off a road and knocked down power lines serving the NE corridor. No power or signals but fortunately no train accident. So things can happen that the train operators have no control over.
