High Speed Railway Rail Fastening System Technology
Fastening systems for high-speed railways are divided into two categories, one is ballasted track fasteners, and the other is ballastless track fasteners. Ballasted rails mainly adopt three types of fasteners: spring clip type-IV, spring clip type-V, and spring clip type-FC.
A rail fastener is the part used to connect the rail and sleeper on the track, its function is to fix the rail on the sleeper, maintain the gauge and prevent the rail from moving vertically and horizontally relative to the sleeper. Fastening systems for high-speed railways are divided into two categories, one is ballasted track fasteners, and the other is ballastless track fasteners. Ballasted rails mainly adopt three types of fasteners: spring clip type-IV, spring clip type-V, and spring clip type-FC.
According to the basic form of the rail, they are divided into the shoulder and non-baffle fasteners, spring clip type-IV, and spring clip type-FC is a sleeper without shoulder fastener, and the elastic type-V is a sleeper with a shoulder fastener. The ballastless track mainly uses WJ-7, WJ-8, W300-1, and SFC fasteners. According to the form of a ballastless bed, it is divided into non-shoulder and shoulder fasteners. WJ-7 and SFC are Fasteners without shoulders, WJ-8 and W300-1 are fasteners with shoulders. Before installation of the rail fasteners, what should be prepared in advance, what’s the correct installation sequence, what should pay more attention to are introduced very detailedly.
