Urban transportation currently has a very important or crucial role because it is one of the factors that strongly support the ongoing economy. One of the transportation modes that is currently had a very high demand in Greater Jakarta is Kereta Rel Listrik (KRL). KRL need to provide not only availability and facility, but also focus on reliability and safety. Had a good operational strategy, especially in the maintenance of rolling stock should be done. Reliability centered maintenance (RCM) is one of approach to optimize the rolling stock maintenance practices given that several critical components have been operating for certain number of periods. The maintenance concept that focuses on reliability brings a good on determining treatment decisions or maintenance strategies. It is also minimized the technical problem in operation by knowing its failure mode. Purpose of this research is to provide an overview of the reliability concepts for rolling stock maintenance from several research journals. This paper contains of several up-to-date literature for improving the effectiveness of rolling stock maintenance from each case of journals and papers. Future maintenance work is based on establishing reliability-based systems. To provide high reliability rolling stock, it is important to introduce reliability analysis methods and to make use of new management indices that consider the impact of faults on transport and cost performance.
