Current railcar inspection practices are intended to identify defects prior to failure, but they generally do not provide predictive maintenance capabilities due to the limitations of manual, visual inspection. As a result, automated condition monitoring technologies (ACMT) have been developed to monitor rolling stock condition and facilitate predictive maintenance strategies. Through improved railcar condition monitoring, these technologies have the potential to reduce: equipment-caused derailments and in-service failures (ISFs), train delays and variability in mainline operations, and operational waste in railroad terminals. In this thesis, I applied lean manufacturing methods to the railcar maintenance process, quantifying both direct and indirect waste. To assess benefits to mainline efficiency, I used dispatch simulation software to quantify the length and variability of equipment-caused ISFs as a function of traffic level. To assess benefits to terminal efficiency, I compared the railroad terminal to a manufacturing production system and used lean production techniques to identify sources of waste and variability. The results of these analyses indicate that the cost-savings from improved mainline and terminal efficiency through the use of ACMT are comparable in scale to the cost-savings from the potential reduction in equipment-caused derailments.
