When studying the dynamic behaviour of a railway track, the accurate modelling of the behaviour of railpads is important. Here a fractional derivative railpad modelis included in a railway track model. The response of the track model to a force traversing the track at a constant speed is calculated by use of a time integration method. Both a constant traversing force and a force modelled as a stochastic process are studied. For comparison an ordinary railpad railpad model with a discrete elastic spring and a discrete viscous damper in parallel is also used in the track model. The calculated displacements when using the two diffrent models are similar. A non-linear railpad model is also implemented, and is found to result in a slightly different response.
