Population concentration and the resulting traffic jams are a common phenomenon in modern society. Such problems are getting worse as time goes on. Although the highway area increases every year, traffic jams still can't be solved effectively. So the popularity of land transportation is decreasing in favour of track transportation. Track transportation has many advantages, but the noise and vibration induced from the wheel/rail contact are sensitive to the neighboring residents along the track route.There are many complaints about noise and vibration from the residents along the Taipei MRT (TRTS) line where the TRTS tunnel is underneath the building, so TRTS decided to use one of best solutions to vibration prevention available to the track engineer -Floating Slab Track (FST).In this paper, the overall issues of the FST based on consideration of the local area in the design stage were studied, including the mode of structure analysis, the vibration isolating component, material, localized geotechnical parameters, rail fastener, elastic coefficient, etc. We hope this paper can share our practical experience and the results of the study for the vibration prevention in track at the urban transportation for environmental pollution prevention, to other railway systems or to academia in the environment field and railway field.
The railway system with its high capacity, low energy consumption, comfort and punctuality now is the main stream of the inland transportation system around the world. The high cost and heavy load of the maintenance work of the traditional ballast track system have attracting the attention of the recent studies. The results of the research have come to a common conclusion that in the future the ballast track system will be replaced by the non-ballast track system. This paper elucidates the development history of the non-ballast track in the local railway system including Taiwan Railway Administration Bureau (TRA), Mass Rapid Transit System (MRT), High Speed Railway (HSR) and Light Rail System (LR), etc. The trend of future development of these systems under the influence of world-wide development of non-ballast system as well as the characteristics of the local area and technical capability of the existing system are also discussed in this paper. The recommendations and suggestions are proposed as references for the research work and real practice of the domestic and international railway industry.
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.
