In this research, a software-based approach was used to study the derailment of a freight wagon with a three-piece bogie. The results show that derailment can occur at the beginning and also at the end of the curves. Disturbance and chaotic lateral movement of the wheels at the end of the curves cause derailment. To avoid this problem, use of low speed in long curves is suggested. It is to be noted that defining a suitable speed for a curve needs repetitive simulations by varying speeds. Critical axle of a wagon is the first axle in the front bogie, from which the derailment starts. As for the software sets used in the study, those interested in derailment simulations should note that ADAMS/Rail is a user-friendly software by which modelling a bogie and wagon can be done even with a little dynamics knowledge, while MATLAB needs all aspects of a physical model, since the model should be built from base.
