ABSTRACT: A Monte Carlo simulation of certain aspects of rail inspection is presented. The simulation is used to compare alternative practices in railroad rail inspection programs. The results how that equipment performance and/or inspection frequency control service defect rate and suggest that allowance of delayed remedial action on non-critical defects can potentially improve detector car utilization.
