Railway Safety, Railway Signaling System Evaluation, Cicalengka Accident Mitigation, and Railway Travel Procedure Updates

Abstract

Abstract
study evaluates changes to the railway signaling system on the Cicalengka route following an accident incident to enhance railway operational safety and reliability. The research background is based on the critical importance of signaling systems in accident prevention. The literature review examines railway signaling system developments, accident causation analysis, and international safety standards. The methodology employs a case study with qualitative and quantitative approaches, including analysis of accident investigation documents, field observations, interviews with operational staff, and system performance simulation. Results indicate that the implemented signaling system changes—covering interlocking upgrades, addition of automatic train protection (ATP), and communication procedure modifications—have improved safety factors by 47%. Analysis of post- implementation operational disturbance data shows a 68% reduction in near-miss incidents over a six-month period. The study concludes that integrating advanced signaling technology with comprehensive procedural training significantly reduces operational risks, although continuous evaluation is needed to address technical and human resource challenges. This research contributes to transportation systems engineering literature by providing a post-incident evaluation model adaptable to Indonesian railway infrastructure contexts.
