Forum:Train track spot on Storm

Ok so I was playing today and saw a guy in this train track spot where you shouldn't be able to get to. It was behind that one building that you can smash the windows and fall through the ceiling. The fenceline stops and there is a little hill with a train track that runs through it. Anyone know how to get up there? The only way I can think of is to have someone else shotgun propell you up it. If there is an easier was to do it alone let me know.
