산악트램 주행을 위한 매립형 콘크리트 궤도의 레일 탄성충진재 개발

초록

A mountain tram is a public transportation system that operates on embedded tracks laid along steep and curved roads. In this study, an elastic rail fastening filler was developed specifically for mountain embedded tracks, and its performance was validated through a series of tests. The filler's usability was confirmed by applying it to a test track. This innovative filler material combines an inorganic binder with polyurethane, enhancing temperature resistance while providing vertical and longitudinal stiffness suitable for mountain tram systems. Using the filler, embedded track models were fabricated, and stiffness tests were conducted in accordance with railway standards. The results verified that the design criteria were satisfied. To further assess filler performance, filler was applied to an actual embedded track featuring steep and sharp curves. A test run using a trial tram was conducted, demonstrating excellent usability and strong resistance to weather conditions.
