I think the best way to do this is build a list of scalectric style track parts in 3D - including grooove, but make the groove twice as deep as it normally is. Then we use the CreateTriMesh code as seen in the examples, toy convert our list of track parts into a single mesh and output the result to ODE.
Then, you could get away with having a proper car with pin in the groove.
To this end, you'll need to start playing with the examples.... I think it can be done in ODE if you're careful and you make the slots deeper than they need to be (and pins slightly longer) to give ODE more of a chance to remain stable.
