Models for probability of derailment are developed based on undetected rail breaks and poor track quality using Petri-Nets and Monte Carlo simulations. The Effect of inspection intervals on lowering the probability has been analysed. The performance of the model is illustrated by an example from a track section of the iron ore line of Banverket (Swedish National Rail Administration).Inga fysiska exemplar för denna post
