I always thought there is a system of rail signals which should prevent accidents like this always in place, like dividing railroad into sections, turn on red light if the next section is occupied, yellow before that and so on...
Did it fail somehow which lead to this accident? I think such systems must be redundant enough to survive even without power/computers?
