Performance Evaluation of Swing-Nose Crossing Turnout on Slab Track (2)

콘크리트궤도용 고속분기기 성능평가 (2)

In order to commercialize the track systems including the turnouts developed in Korea, the guideline of technical and systematic performance evaluation considering local environment was established on Aug. 2010. It consists of a technical compatibility, laboratory test and in-service test. Technical compatibility and laboratory test of the domestically-developed swing-nose crossing turnout on slab track(F18.5) were evaluated according to the guideline. And then in-service test was performed for the turnout installed at the 2nd phase site of Kyung-Bu HSR. In-service test is comprised of monitoring, and field and on-board test during KTX operation, where monitoring is to check the maintainability, and field and on-board test is to confirm structural and running safety. This paper is intended to explain the requirements for the in-serve test and analyze the results of monitoring and the data measured at field and on-board. Based on the in-service test, it is proven that performance of the domestically-developed swing-nose crossing turnout on slab track(F18.5) well satisfies the requirements of the guideline.
