You're never saved in the trolley problem. You're only saved for later.
I think that just derails the trolley, which possibly injures the people on the trolley but probably less chance than certainty of killing people on the tracks.
who said there is anything in the front of the switched track?
edit: the person dies :(
If only one side of the switch/points remain, depending on the type of crossing and condition of the wheels, there's a chance that the trolley's right side wheels can jump over the switch and continue straight forward, even as the switch is set to diverge onto the non-existent siding.
Or it could derail but continue barreling forward anyway. But trolleys don't tend to be going that fast.
