This paper investigated the effects of multiple wheelsets of bogies and their separated distances in the multiple passenger cars on dynamic response of subsoil at the critical speed. To simulate this condition, two-dimensional dynamic finite element analyses were used. For the present purposes, the simple train vehicle model, which has been developed previously by authors, was extended such that the train vehicle model has up to three passenger cars. The car-body mass and wheel are connected via a spring-dashpot. The wheel numerically represented by a reference point was interacted with the rail beam via the nonlinear Hertzian contact model. The slab track and subsoil were modeled using continuum elements bounded by special infinite elements. To observe the effect of the train speed of one, two, and three passenger cars, Rayleigh wave velocities in the subsoil were observed. Numerical results from time-domain simulations show that dynamic response at the critical speed becomes notable when the train vehicle has more than three passenger cars.
