The function of a rail fastening system is to secure the rail to the sleeper or tie. Typically, a rail fastening system consists of anchors, sleeper plates, baseplates, fasteners, spikes, screws, bolts, and other components.
Rail fasteners should effectively maintain a long-term reliable connection between the rail and the sleeper while fully utilizing their cushioning performance under dynamic loads to delay the accumulation of track residual deformation. The railway fastening systems provided by GNEE RAIL possess sufficient strength, durability, and a degree of elasticity, featuring simple structures that are easy to install and remove. We can supply various types of railway fastening systems, including SKL, KPO, Fast, Fist, Nabla, WJ-8, and others.
