Vibration is produced in the ballast and the road bed when a train passes. We define the "Ballast Breaking Velocity" of the wheel on the track as that velocity of the train which produced an upward acceleration of the ballast equal to the downward acceleration of gravity. In this paper the author has explained the development from experiments made on the subject and investigated the flexural vibration of the straight beams with uniform cross section on elastic foundation under the action of various forces, and has tried to apply these results to rail and tie. And in this paper, by using energy method, the fundamental solutions have been induced most generally. That is, dealing with generalized coordinates, generalized forces and Lagrange's equations, the author obtained the solution concerning the generalized coordinates by the method of variation of constants. Then, by applying these results to rail and tie, in the first instance, the calculation of the rail under the action of a train has been carried out.
