If one has accidentally flipped a trolley lever and found oneself unable to catch up with the thing (possible with high level athletics) one can simply sit back and wait until the trolley has reached its destination, at which point the lever will flip back. One can then flip the lever again and the trolley will return.

Kraokendon works as a hurled weapon with the effect that it will return to the hand of the thrower. Beware, though, it often crashes the game.
