What's required to rotate the axle is a torque, not a force.
And, given rolling element bearings, it probably depends more on the local grade of the rail and the eccentricity of the wheel than on anything else.
I.e., for imperfect parts, it's an inclined plane problem, but it may be hard to find the geometry of the plane.
For perfect parts, there are equations here:
