This paper addresses the dynamic response of a railway tracks under moving loads. In the present analysis,an infinite Euler–Bernoulli beam of constant cross-section resting on an elastic foundation is considered. The beam andfoundation are assumed to be homogeneous and isotropic. The foundation is modeled using one and two parameters withdamping. The beam is subjected to a constant point load moving with a constant speed along the beam. An effort hasbeen made to find the solution of the governing differential equation analytically. In this parametric study we find thatthe deflection and bending moment response of the beam is symmetric with respect to point load in the case of withoutdamping and asymmetric in the case of damping. The maximum displacement as well as maximum bending moment bothoccurs under the moving load for both the cases with or without damping.
