The article investigates the influence of the preventive maintenance on the reliability and availability indexes of the railway means of transport. The research was done using the method based on fault tree analysis (FTA) and the Monte Carlo simulation. The authors performed a cause and effect analysis of the occurrence of undesirable events during the operation of selected vehicles. They identified the weakest components of the rail vehicle that affect the downtime and mean availability most significantly. Specialised software including Weibull++, BlockSim and MiniTab aided calculations were used to illustrate the application the results of a modernisation project involving a 6Dg diesel locomotive, carried out in cooperation with the biggest Polish rail carrier. The evaluation of reliability and availability was based on real operation data of a selected sample of 75 locomotives. The obtained results indicate that the proposed solution has a wide applicability potential.
