Global Non-Ballasted Rail Fastener Development Base on Taiwan Experience

Abstract

Taiwan has been active in construction new railway system in recent years and, furthermore, several old railway systems are undergoing overhaul. The trackwork engineering will be one of the major key to decide whether the railway was successful or not, Now-a-day, All the railway systems in the world are concentrating on improving the trackwork system being a safety, longer service life, low maintenance, low environmental pollution. The international track work field was concentrating on the development of non-ballasted (Direct Fixation) track, because it highly automatic efficient and low maintenance. This paper was study the Taiwan non-ballasted (Direct Fixation) track rail fastener (DFF) experience and it's localized production and development, and the DFF experience of other railway systems.This paper was base on the accurately experience and achievement of Taipei mass rapid transit system (TRTS) to study the DFF, This paper was specially point out the DFF test plan and the acceptance criteria, it was base on the TRTS character and the simulation of accurate operation that conclusion was discuss among TRTS, Chung San Institute of Science Technology, Industrial Technology search Institute. We hope that our direct fixation rail fastener experiences, special in the test plan, can share with other railway systems. This experience can help the future development of non-ballasted track and DFF.
