Abstract：A mathematical model of railway track with a section of unsuppor ted sleepers is developed. Based on this model, the equations of motions of trai n-track system involving nonlinearity, due to nonlinear contact forces between wheels and rail, are solved by using direct integration method in time domain to obtain nomerical results. Dynamic responses of track components to the hung sec tion excitations are treated. The results show that high acceleration in sleeper s and large wheel-rail contact forces occur if there are rail corrugations in t he hung section.
