Various deformations taking place in the track due to the lateral force of rolling-stock are theoretically and experimentally analyzed; the critical value of lateral force to destroy the track is proposed; and the results of application of research data are summarized. It is found that the rails in the track may be regarded as supported on three kinds of springs, and these springs are related to the rail pressure under wheel weight. The three springs include first, a spring due to transverse deformation in the wood sleeper near the rail base, or a transverse spring of elastic rail fastening; second, a spring due to the lateral displacement of sleepers in the ballast; and third, a spring due to reaction of a wood sleeper to the inclination of rail by twisting, or a spring of elastic rail fastening to rail inclination. Thus, the track deformations under lateral forces might be regarded as the deflection and twisting of rails supported by these springs.
