Nabla Railway Fastening System
The rail fastening system is an essential component of the railway track structure, consisting of various track fastenings , among others. Its primary function is to securely fix the rail to the sleepers or track slabs to ensure track stability. GNEE RAIL offers various types of railway fasteners, such as rail clips,rail anchor,rail tie plate, dog spikes, fish plates, bolts and nuts, tie plates, etc. In addition to providing standardized products, we can also offer customized services based on customer requirements.
The Nabla fasteners system is a safe and reliable system most widely used in Europe. It can be applied to tramways, light rail, subways, mainlines, and high-speed railway tracks. The unique shape of the Nabla fastener generates a dynamically stable axial load on the rail when the nut is tightened.
