High Speed rail refers to a rail capable of carrying a train that reaches passenger line speed at 350km/h (axle load less than 170kN) or mixed passenger and freight line speed at 250km/h(maximum axle load is 230kN). GNEE RAIL could supply high speed railway fastening systems including Type WJ-8, Type WJ-7, Clip V and Clip IV.

Type wj-8 elastic clip rail fastener system

The WJ-8 elastic rail clip fastener system is suitable for passenger lines with a maximum axle speed of 350km/h and a CRTSII type ballless track with a shaft weight of 170KN (considering that the axle weight may increase by 10%). The WJ-8 fastener system has been applied to multiple locations and is generally in good condition.

Type wj-7 elastic clip rail fastener system

WJ-7 type fastener system is a kind of ballastless track fastener system developed to meet the technical requirements of passenger line, it is a special fastener system for laying all kinds of non-shoulderless track, which is optimized based on WJ-1 type and WJ-2 type ballastless track fastener system. The fastener system can be applied to sleeper-buried (double-block sleepers and long sleepers) and slab ballastless tracks on bridges, tunnels and subgrades.

Type V rail clip fastening system

The elastic clip V-type fastener system is a rail fastening system for retaining rails with shoulders. The fastener system consists of spiral screw spikes, flat washers, spring steel rail clips (W2 type, X3 type and A type), Rail Insulators, and steel rails. The lower plate (the rubber pad and the composite pad) and the pre-embedded casing positioned on the prestressed concrete shoulder sleeper. Adjust the height of tie plate when adjusting the height of the rail.

Type IV rail clip fastening system

The rail clip IV fastening system is a boltless railway fastener system, which is an elastic non-split fastener without concrete shoulders for sleepers.
