- Provision of reliable rolling stock and infrastructure equipment is an important part in achieving high levels of safety. Therefore, the railway industry uses different methods and tools to improve the performance of different subsystems in order to ensure safety and reliability, which are the important factors for passengers and cargo transportation. Hence, reliability analysis is required to identify the bottlenecks in the system and find the components or subsystems with low reliability for a desired level of performance. This paper focuses on collection and analysis of field failure data over a period in Raja Passenger Train Company of Iran. The results of data analysis show that wheel sets is the bottleneck, and it utilizes the historical data of wheel sets to determine the reliability function. Thereafter, the reliability of each type of wheel sets are identified over different time intervals and which can be used to determine the appropriate time of preventive maintenance tasks.

- 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 maintenance tasks, etc. Therefore, it is essential to develop effective maintenance strategies to deal with these problems. While the safety is a significant factor in rolling stock industries, the most well known and widely applied maintenance optimization strategy is so called Reliability Centered Maintenance (RCM). The aim of this paper is to discuss the implementation of RCM to make maintenance of rolling stock of the Raja Passenger Train Corporation more cost effective. Therefore, the paper presents RCM implementation for the wheel sets which is the most critical subsystem from the rolling stocks reliability point of view. Finally, it recommends a modified maintenance plan which is able to improve the maintenance productivity by decreasing downtimes of passenger coaches.
