Ballastless track is generally used in the track structure of suburban railways,so a ballastless turnout fas-tening system is designed.The elastic cushion under track slab of turnout fastening system adopts ethylene propylene diene monomer(EPDM),which realizes the low stiffness requirement of ballastless track bed.The composite eccen-tric sleeve with anti-rotation function and cover plate with anti-rotation function are arranged at the bolt installation position of turnout sleeper,which can increase the adjustment range of turnout gauge,improve the stress of bolt at turnout sleeper and enhance the stability of fastening system.The trial production and performance test of the fasten-ing system show that all the indexes of the fastener system meet the requirements of the code and have good vibration reduction performance.
