The railway fastener system is a key device to achieve reliable connection between rails and sleepers. Its core function is to fix the position of the rails, maintain accurate gauge, and evenly transfer the train load to the sleepers and lower foundations. The system consists of buckles, pads, anchoring parts, etc. According to different design and performance requirements, it can be divided into SKL, KPO, Nabla, WJ-8 and E-type.

KPO Railway Fasteners system: adopts a gusset plate and bolt structure. The gusset plate covers both sides of the rail and is connected to the sleeper by bolts. The gusset plate of the KPO system has various shapes and specifications, which can be selected according to the models of rails and sleepers. It has a simple structure and is easy to install and disassemble. It is suitable for daily railway maintenance, line reconstruction and temporary track laying. For example, in the construction of special sections such as railway bridges and tunnels, the KPO system can quickly adjust the position of the rails.

Nabla Railway Fasteners system: It consists of springs and elastic pads. The springs are made of alloy materials, are thin and elastic, and are in close contact with the rails; the pads are made of rubber or polymer materials and have good vibration reduction performance. The Nabla system can effectively reduce train running noise and vibration through the synergistic effect of shrapnel and pads. Therefore, it is widely used in urban rail transit, such as the New York Subway and the London Subway, to reduce the impact on surrounding residents and buildings.
