Which is what I just did (couldn't resist).
Hacking OpenDE apps can be so much fun!

The model contains 44 track segments, with 44
hinge joints. The traction is accurately simulated
by having the spokes of the rotor collide with the
track segments.
As you can see in the vid: performance is excellent,
and sim remains stable at higher speeds. (5ms stepsize).

A testament to the quality of ode, I think.
