Doesn’t sound too fail-safe to me.
I really do believe no train should be left running with no one in it.
Engineers (not train drivers) have a saying: Every time that you make something "fool proof", God makes a more talented fool!

It happens more often then you might suspect, 99.9% of the time it doesn't matter. It's that 0.1% that bites. There are times when it's unavoidable, I would think it a better policy to chock the wheels just to be sure. Trains have four braking systems and that should suffice. This time it wasn't enough to quell the perfect storm. Very sad...
