Planning and construction of the Taipei Metropolitan Mass Rapid Transit System has been ongoing for 20-plus years. During the planning and design stages, based on cases performed in other countries, DORTS carefully evaluated the impact of noise pollution and vibration caused by MRT trains on adjacent buildings to ensure that structural damage would not be caused. However, with the public's environmental awareness rising and the demand for a high-quality living environment increasing, complaints about noise pollution and vibration come with the operation of each MRT route.To reduce noise and vibration arising from MRT tracks, floating slab tracks (FST), a 30-yearold and well-recognized vibration-reducing technique used abroad, has been introduced for the first time in Taiwan in the construction of the Xinzhuang and Luzhou lines. The application of FST not only creates a high quality MRT system but offers an undisturbed living environment for residents along the MRT routes as well. This article aims to keep a complete record of the construction of the FST demonstration section, the first ever in the nation, for readers' reference.
