What a mess! Part of the death toll will have been caused by carriages falling from the bridge.
Cause of the accident appears to have been due to the following train exceeding its block authority when the train in front stopped due to power outage caused by lightning strike and so ramming the rear of the stopped train.
It is possible that the safety curcuits may have been fried by the same lightning strike, but I would have expected that such curcuits would have been protected from lightning. However lightning strikes are a frequent event and so must be designed for. My speculation only, no proof at the moment.
The thing that really spins me out was the 1300 to 1400 passenger figure.
