What rail fastenings are compatible with rail pads?
Rail pads can prevent rail sleeper abrasion and the crushing of the sleeper under the rail foot. Rubber rail pads are normally designed to a specified load-deflection characteristic. The initial stiffness of the rail pad is designed to be low so that that their deformations under the springs toe loads is quite substantial.
Rail pads are compatible with various fastening systems, working with rail clips (like E-clips, SKL clips), baseplates (tie plates), screws (screw spikes, T-bolts), insulators (for gauge/current), guide plates, and sometimes directly with sleepers (concrete/wood) to absorb shock, reduce noise, and protect components in systems like E-Type, SKL, Fast, Fist, and WJ.
Common Rail Fastening Systems Using Rail Pads:
- E-Clip System: Pads work with E-clips, insulators, and shoulders on concrete sleepers to provide elasticity and reduce vibration.
- SKL System: Pads used with SKL clips, screw spikes, dowels, and guide plates for quiet, elastic track.
- Fast System: Uses spring clips and pins, with pads between the rail and sleeper (rubber, EVA).
- Fist System: A clamp-type system where pads absorb impact.
- WJ Type (e.g., WJ-7): Used for ballastless tracks, incorporating various pads and components like T-bolts, clips, and tie plates.
- Direct Fastening (Japan): Pads used with T-bolts, spring blades, and baseplates on concrete slabs.
Rail pad functions
A rail rubber pad is essential in reducing shock and vibration in a rail system. The pad laid under the rail to ensure:
Load distribution over a larger surface
Elimination of load concentration and the resultant fatigue stresses
Centering of loads on the supporting element
Absorption of uneven contact surfaces between rail and support
Reduction of noise and vibration
Sealing between the bottom of the rail and the top of the support
Reduction of wear of the rail and its support
As a professional manufacturer of rail fasteners, GNEE RAIL is able to produce rail pads of various rail pads, such as UIC54, UIC60, BS80lbs, BS100lbs and so on. In addition, we can offer custom-made track pads according to drawings or samples.
