    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.

    I was referring to the London Underground system which IS failsafe. I worked on the system and know only too well.

    First of all the number of signals could have been three, in this instance it could easily have been one. Have you been a signalman? Have you worked with these systems, I would think not given the possible inaccuracy of your post.

    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.
    So now you are assuming one had less safety than the other, where is your evidence? What regulations and what do they say.

    We all know that... seems you like to rant for the sake of it.
