Abstract
Track damage and its evolution depend on the vehicle-track interaction: different vehicles have a different impact on the track. For track maintenance to be effective, planning should take into consideration the impact of the vehicles running on the track. This work proposes a new approach to improve monitoring scheduling for track inspection, which includes considering the activity variation on the track. The idea is to create numerical models of the different vehicles that usually run on the track; these models, designed using multi-body codes, are then used to analyse the impact of different vehicles on various sections of the track.
