Why do you want to use a physics library for this? If you want to use
fake physics, you don't really need ODE I think... why not make a
physically realistic train simulation, with the tracks as boxes, and
construct the wheels from ccylinders the way real trains have, with an
edge on one side of the wheel to keep the train on the track. That way
you'd get everything from the little jolts between the track "gurders"
to realistic de-railing and friction. Wouldn't that be cool? :)
