MAINTAINABILITY ANALYSIS OF DIESEL-ELECTRIC LOCOMOTIVES

This paper deals with the effectiveness of preventive maintenance of diesel electric locomotives. The effectiveness can be considered in several different contexts. It can be considered qualitatively, as a reduction in the frequency and severity of locomotive component failures, or as a statistically significant change in the probability of failure-free operation over a given number of locomotive-miles (i.e. reliability). As the implementation of various preventive maintenance techniques and procedures ultimately requires an additional expenditure of capital, the benefits incurred by an improvement in reliability, such as a decrease in maintenance expenditures required to achieve a given level of operational reliability, or a decrease in required locomotive-fleet inventories proportional to lower accumulated fleet down time, must ultimately be quantified as a monetary benefit, and weighed against the associated cost penalty. Each of these approaches is explored in this analysis. The methodology is applied to cost-effectiveness of testing of diesel-electric locomotives for predictive and preventive maintenance of electrical subsystems using SEARCH (System Evaluation and Reliability Checker). It is shown that the application of SEARCH could result in cost-savings as well as improved performance of locomotives.
