how is that possible? o_o pretty much all looped roller coasters I've seen don't have anything to stop a car on a loop, they'd just roll through it and stop later. A rollor coaster is pretty much a free rolling train. if they were to get stuck it would have to be either the car lost momentum or stopped in one of the ratcheted belt sections. Getting stuck in a loop is not physically possible unless there is a ratchet there. Even if it were to lose momentum, it would just roll backwards.
