Thanks! I will try that out. Since you are having problems with collision, What if you make your tracks not completly solid? This may be a crazy idea (may not even be possable).What if when your train starts turning, instead of it pushing against the track, it "sinks" into the track. The train would start going into the track, however, the track will be pushing it back out. This would mean the track isnt completly solid, but almost solid. The farther you go into the track, the harder the track pushes your train. I dont know if this is completely out of the realm of possablilities, but its just an idea.
