I was walking around because I heard that the snowmobile gets stuck really easily so I parked it on the side of the Hill. May I suggest a unstuck command that would put you next to the snowmobile if it's within a certain distance. And then if you're on the snowmobile and you get stuck it would just teleport you and what ever your riding away from where you're at. Possibly in the air and invulnerable to fall damage incase scripting the unstuck is too complicated to place the person on the train without falling through.
