Abstract

The development of automatic railway signaling systems that use moving block systems has grown rapidly. The moving block signaling system, which is a development of the fixed block system, has functions such as automatic control, shortening headways, increasing operating capacity, and railway safety. The Technology used in the moving block signaling system must be reliable and suitable for passenger comfort and safety. So, an effective and efficient maintenance method is needed. Planned and scheduled maintenance prevents disruption and gives minimum maintenance costs. The condition-based maintenance, on the other hand, is the right maintenance for an automatic train signaling system because it uses a data-driven model so that it can support decisions in determining maintenance strategies, and maintenance can be optimized using the Reliability, Availability, Maintainability, and Safety (RAMS) method with one of the Reliability Centered Maintenance (RCM) analysis tools. This optimization can increase operational safety, maintenance cost efficiency, and asset availability. In addition, another advantage of this RCM method is that it can identify critical components that require maintenance priority, so that maintenance resources can be optimized.

Abstract

Track infrastructure plays an important role in the railway business, where the safety of rail travel is determined by the integrity that exists in each component of the railway track. In this paper, an integrity assessment of track infrastructure is carried out using the Failure Modes and Effects Analysis (FMEA) method by identifying various failure modes for each component and track geometry that have existed in the field. Then a survey was conducted to track maintenance experts at PT Kereta Api Indonesia (Persero) to get the value of severity, occurrence, detection, and recommended actions taken. Based on the analysis, the failure mode with the highest Risk Priority Number (RPN) is the cracked rail on the welding/fish plate joint with a value of 280, while the failure mode with the lowest RPN is the loose rail with a value of 108. Then 21 failure modes fall into the "unacceptable" risk level, 4 failure modes fall into the "tolerable" risk level, and 1 failure mode falls into the "acceptable" risk level. From the results of this assessment, it is expected to help in prioritizing the risk of failure, so that the maintenance strategy can be planned properly, and the safety of train travel can be maintained.

Abstract

Railway tracks are complex assets that require a comprehensive and integrated management approach to improve service quality in the era of modernization of the railway industry. The RAMS (Reliability, Availability, Maintainability, and Safety) method is one of the approaches used in managing railway track to ensure that the railway system operates safely. The discussion in this literature review is categorized into three sections including (1) RAMS on Railway Tracks, (2) RAMS Analysis Tools on Railway Tracks such as RBD, FMEA, FMECA, and FTA, then, (3) Challenges and Future Directions of RAMS on Railway Tracks. Based on the review, research related to RAMS in railway tracks is limited due to the complexity of the railway tracks. However, the formulations and principles of research associated with RAMS on railway systems can be adopted in the analysis of RAMS railway tracks because the principles generally apply to railway systems including railway tracks. The implementation of RAMS on railway tracks can be used as a reference to improve the performance of railway track assets and provide long-term benefits by minimizing costs due to accidents or catastrophic failures for the Indonesian railway industry.
