Applying RCM strategy for productive consideration in rolling stock workshop A case study in RAJA Passenger Train Co.

The proper maintenance strategy is the significant concern for rolling stock companies. Historically, most of the maintenance tasks in rolling stock companies are devoted to Preventive Maintenance which leads to some problems such as erroneous maintenance work, unnecessary and conservative maintenance tasks, etc. Hence, it was essential to develop the new strategies to deal with these problems. While the safety is the significant factor in rolling stock industries, the most well known and widely applied maintenance optimization strategy is Reliability Centered Maintenance (RCM), which has its origins in the aerospace industry.So this paper introduce the RCM strategy which offers the most systematic and efficient process to address an overall programmatic approach to the optimization of plant and equipment maintenance productivity. Moreover, the present paper step by step presents the implementation of RCM methodology in the rolling stock maintenance industry in RAJA Passenger Train Corporation as a case study. In this case study the RCM is performed on wheel set maintenance tasks which is the bottleneck of maintenance works and is the main reason for the high level of passenger coach downtimes in this company. Finally it recommends the new maintenance schedule which improves the maintenance productivity by eliminating the downtimes of passenger coaches.
