[quote=Ronin;3204301]The system used on that track does allow humans to interfere. So it cannot be failsafe. Yes the signalling system is there and even when the automatic braking system was switched off it still takes the drivers to ignore at least two signals each. That is both drivers as both trains were moving at cruise speed. What happened requires a long list of human errors.
The tracks belong to Deutsche Bahn and are operated by them. The two trains are of one private operator. This should not have contributed to less safety at least in theory and according to the regulations.
The trains have black boxes and evaluating them will show the whole picture eventually.
