| Abstract | A Monte Carlo simulation of certain aspects of rail inspection is presented. The simulation is used to investigate alternative practices in railroad rail inspection programs. Results are presented to compare the present practice of immediately repairing every detected defect with an alternative practice under which repair can be delayed for defects not exceeding a specified size. The sensitivities of inspection vehicle utilization and rail failure rate to variations of inspection frequency, repair gang capacity, and traffic tonnage are presented. A risk/benefit assessment of delayed action, relative to present practice, is developed and carried out to compare the risk of rail failure due to incorrect classification of defect size with the benefit of rail failure prevention due to increased opportunity to detect large defects. |
