Train & dumper

This example showcases the modeling of a long heavy haul train through a dumper, which allows simulation of train longitudinal dynamics. This model can be used to optimize dumping strategies for trains through a typical dumper. Field measurements using instrumented cars were used for the validation of this model. The model allows investigation of the influence of different operational parameters on in-train forces.
