The rolling stock might function at an optimum level in reliability, availability, maintainability, and safety with comprehensive maintenance. The past decade has seen rapid development in the management of maintenance costs in many sectors such as the automotive and aviation industry. However, there is a lack in a number of studies focusing on rolling stock maintenance costs. This article provides comprehensive knowledge on the rolling stock maintenance cost. Recently, the research found no specific literature reviews that focus on typical rolling stock maintenance costs. This paper attempts to review, identify and discuss the influential costs involved in rolling stock maintenance. This research systematically reviews and classifies a substantial number of published papers and suggests a classification of specific cost categories according to rolling stock needs. The results revealed that 27 variables have contributed to the rolling stock maintenance costs. The highest among the influential costs are 13.8% spare part cost, 11% life cycle cost, 6.4% preventive maintenance cost, and 4.6% for the workforce, corrective maintenance, and cost of ownership, respectively. The interrelationship between influential costs and their effects on rolling stock costs is further discussed. More importantly, the paper is intended to provide a comprehensive view of influential costs affecting rolling stock maintenance and give useful references for personnel working in the industry as well as researchers. This research has highlighted the possibility of future major studies to minimize the identified maintenance cost and industry to optimize its operational cost. [ABSTRACT FROM AUTHOR]

This research aims to analyse, evaluate and rank the maintenance strategy practised by the train operating companies, specifically by the rolling stock maintenance team. A quantitative method was adopted for data collection. A total of five train operating companies were chosen to participate in a survey that has been carefully designed. The research first identified the maintenance strategy associated with the rolling stock maintenance through systematic literature reviews. Afterwards, six maintenance strategies adopted by the companies were identified. The type of maintenance strategies identified was used to structure the survey questionnaire. Judgemental sampling was utilised for sampling purposes. Finally, the data collected from the survey were analysed using an importance index to complete the ranking analysis. The research discovered that corrective and preventive maintenance strategies are the most commonly adopted among the five Malaysian train operating companies. This study also highlighted the factors that future studies should consider to establish predictive cost models for rolling stock maintenance. [ABSTRACT FROM AUTHOR]
