How do head-on train collisions still happen? Would it not be fairly inexpensive to mount multiple cheap sensors in the tracks that start broadcasting warnings when two trains are heading towards each other? Even with sensor failures the sheer number of them would be able to detect the problem well in advance. No reason to expect rail companies to have any more foresight than any other company these days. Everyone just wants to look at the results for next quarter.
