Thanks guys. Its alright. I do have the parts to fix it. Just haven't gotten around to it.
What happened was, I was blocking the engine facility electrically(I don't have Dcc...yet!), and was checking one of the "dead tracks" to see if the DPDT switch was connected right. The GP60(Which I super-detailed from a basic Athearn BB) was sitting on the track I was testing. With the powerpack set at "run 8", it just sat there. When I flicked the switch to the "on" position(forgetting where the throttle was set at), the loco took off, down an unfinished branch line and right off the edge of the layout.
So basically...It was operator error.
Another tip: Good to use those cheap Bachmann "Buy A Loco, Get A caboose Free", toy store deals when testing track.
So..once wrecked.....
