Dynamic interaction between a railway freight vehicle and a switch and crossing (S&C) is studied by simulations of vehicle dynamics. In particular, the influence of a stochastic spread (scatter) in traffic parameters on damage in the S&C is assessed. The considered parameters are wheel profile and wheel–rail friction coefficient. To form a database for sampling, 120 wheel profiles from freight wagons in regular traffic have been measured and categorised with respect to wear. Among the investigated parameters, it is shown that equivalent conicity is the wheel profile parameter correlating best to damage in the S&C panels. The influence of hollow worn wheels on damage is also investigated, and it is found that such wheel profiles display a different running behaviour at the crossing transition. Convergence properties for samples of runs generated by Latin hypercube sampling (LHS) are compared with the corresponding properties obtained by pure random sampling. It is concluded that the LHS-generated samples exhibit similar or smaller variance in damage compared with the randomly generated samples.
