Abstract: A type of continuously supported embedded rail track system that applied to Guangzhou Metro Line 14 construction is introduced. Through data collected from field tests in 2017 and 2019, performance indicators such as the wheel-rail roughness, vehicle dynamic performance, track structure vibration and noise reduction performance between continuously supported embedded rail track system and common fastening track system are compared and analyzed. Results show that the continuously supported embedded rail track system has good geometry positioning, low daily maintenance workload, and stability in vibration and noise reduction performance. Through maintenance training and drill on the continuously supported embedded rail track system training line, the track system maintenance problems during operation are solved.
