The wheel-rail interaction constitutes a complex kinematic coupling that evolves over time due to various factors such aswear, rolling contact fatigue and periodic maintenance activities, that determine the rail service life. The state of the rail surface after aspecified traffic and tonnage passing reflects the track-friendliness of the vehicles. This is particularly helpful in guiding track accesspricing strategies for different vehicle designs based on the amount of damage they cause to the track. A complex and highly non-linearmulti-body simulation environment is set up and iterative vehicle dynamics calculations are performed, along with the implementationof recently developed wheel-rail contact models, damage models and maintenance procedures over a 100 MGT tonnage period.
