Mohammed, so you are saying that the rail and the wheel touch only along a one-dimensional line, rather than a two-dimensional area? In that case, the contact is pretty simple because the contact area does not actually depend on the solution. You could probably just do that using step-8, for example (also looking at step-18). But that's of course not particularly realistic -- the real contact area does depend on the force in question, as well as dynamic effects due to rolling.
