In this paper, from a view point of multibody dynamics, the modeling and the formulation for development of corrugation on the elastic rail under the motion of wheel with contact rigidity is proposed. The formulation for the rail motion is completed by A.N.C.F. We discuss about the effect of contact rigidity and elastic support on the contact force fluctuation. It is confirmed that the contact rigidity and the elastic support influence on the vibration mode of this system. This leads the fundamental knowledge of the prevention of the corrugation development.
