Metrokapsul is a light rail transit (LRT) mass transportation system with an automation level of grade of automation 3 (GoA 3) which was built by PT. TReKKa (Capsule Train Engineering) and developed with BAMEC (Bandung Mechatronic Center). One system that really supports the automation operating system is the braking system. The braking system coordinates with the main controller in order to synergize with other systems to achieve the need for an operating system that has a high level of automation without compromising the comfort and safety of passengers. As for the demands of SNI IEC 62278:2002 by Badan Standardisasi Nasional (BSN) regarding the need for an analysis of Reliability, Availability, Maintainability and Safety (RAMS) in the construction of railway system. Therefore, it is necessary to carry out a Failure Mode Effect and Criticality Analysis (FMECA) analysis to assess the reliability of the initial design of the metrocapsule braking system. FMECA method presents a table at the component level of the braking system with all the systematic element of failures to make it easier to determine the level of criticality. In doing so, it takes the parties involved in the manufacture of the metrocapsules as resource persons to facilitate filling out the FMECA table. In addition, historical failure rate data obtained through similar braking system data is needed to analyze the criticality level. Components that are included in the high criticality level are also given action recommendations to reduce the high criticality level.
