Types of Rail Fastening System

The rail fastening system produced by our company mainly include the following types:

SKL Rail Fastening System

The SKL Type Rail Fastening System is a robust and efficient solution designed to securely fasten rails to sleepers, ensuring stability and durability in railway tracks.

Fist Rail Fixing System

The FIST rail fastening system is a specialized, elastic rail fastening method originating in Sweden, designed to secure rails to sleepers, particularly in heavy-haul, high-fatigue environments like those in Australia and South Africa. It commonly consists of a unique spring steel "fist" clip, a guide plate, a base pad, and an insulated pin, providing high-reliability fastening.

KPO Clamp Railroad Fasteners System

The KPO Railroad Fasteners System stands as a cutting-edge solution in the field of railway infrastructure, engineered to deliver exceptional performance, reliability, and durability.

Functions of Rail Fastening Systems

Preventing Lateral and Longitudinal Movement
A Rail Fastening System is engineered to prevent both lateral and longitudinal movements of the rails. By securing the rails to the sleepers with rail clips and anchors, the system effectively keeps the tracks in their correct position. This is essential for high-speed and heavy-load railways where any shift in the track alignment could lead to severe accidents.

Enhancing Track Alignment and Load Distribution
The primary function of a Rail Fastening System is to enhance track alignment and optimize load distribution. Railroad tie plates distribute the load from the rails to the sleepers, while rail clips and anchors keep the rails firmly in place. This holistic approach to load management reduces the risk of track deformation, prolongs the life of railway components, and improves the overall stability and safety of the railway network.

Improvement in Passenger and Cargo Safety
A well-designed Rail Fastening System is foundational to improving the safety of both passenger and cargo trains. These systems ensure the rails remain securely in place, preventing derailments that could have catastrophic consequences. By keeping the tracks aligned and stable, fastening systems help mitigate risks associated with high-speed travel and the transportation of heavy or hazardous goods.

Components of a Rail Fastening System

Rail Insulator

Rail insulators are critical railway fastening components installed between the rail, sleeper, and clips to provide electrical insulation, maintain gauge, and reduce vibration.

Rail Clip

A rail clip helps to fasten steel rails to railway sleeps.

E-Type Rail Clip

An elastic rail fastening, or E-clip, is a spring-loaded clip that ensures permanent elastic clamping.

SKL Rail Clip

SKL rail clips are tension clamps that ensure permanent elastic clamping to fasten turnout parts onto concrete bearers.

Fast Clip

Fast clip fasteners are a newer type of rail fastening system. It is shoulder-free and bolt-free, has fewer spare parts, and features a compact structure.

Rail Ties or Sleepers

Railway ties or sleepers sit between two rail tracks to maintain the correct gauge. Early ties were made of wood, such as oak, karri, and jarrah.

Rail Pad and Rail Insulator

The rail pad is an elastic polyurethane mat that is placed between the rail and the sleeper.

Spikes, Screws, and Bolts

Rail spikes are large nails with offset heads that are used to secure rails and base plates to sleepers in the track over the ballast.

Chair Screws

Chairs screws, or coach screws, are large metal screws that are used to screw the baseplate or the rail directly into the sleeper.

Installation Steps of Rail Fastening System

Place Rubber Padding Plate

Position the pad accurately in the sleeper's rail seat to buffer vibrations and insulate.

Install Gauge Retainer

Select the appropriate retainer per design gauge, ensuring tight fit against rails and sleepers to fix gauge.

Mount Elastic Clip

Secure the clip onto the retainer and rail, relying on elastic deformation to generate clamping force.

Tighten Spiral Spike

Use a torque wrench to achieve specified values (e.g., Type II system requires 100–140N·m) to:Prevent loosening without over-tightening damage.

Packaging and Shipping

Packaging	Packed in durable wooden boxes or reinforced cartons. Custom packaging solutions are available for specialized requirements.
Shipping	Shipping by sea, by air, by express are acceptable. According to your requirements.

FAQ

Q: What are the different types of rail fasteners?

A: Types of rail fasteners include spikes (dog spikes, screw spikes), bolts (fish bolts, hook bolts), clips and clamps (E-clips, SKL), and fastening systems like SKL, E-clip, KPO, and Nabla, which are specific combinations of these components designed to fasten rails to sleepers and manage load, vibration, and gauge.

Q: What is rail fastening?

A: Rail fastenings are devices that are used to secure running rails into baseplates or chairs or directly to sleepers, bearers, or other rail supports. They ensure that rails remain fastened to sleepers, bearers, or other rail supports and therefore play an integral role in railroad construction.

Q: How do rail anchors work?

A: Rail anchors, also called anticreepers, are spring steel clips that attach to the underside of the rail baseplate and bear against the sides of the sleepers to prevent longitudinal movement of the rail, either from changes in temperature or through vibration.

Q: What are the requirements of a good rail joint?

A: An ideal rail joint would provide continuity, strength, flexibility, adequate expansion space, easy removal/replacement, and be economical to install and maintain.

Q: What is the purpose of a rail fastener?

A: Rail fastenings are devices that are used for securing rails into chairs or directly to sleepers. These devices fasten the rails to sleepers and facilitate an effective transfer of force. These also ensure a proper slope of rail foot (1:20, 1:40) in the transverse plane.

Q: Why is there a gap at the joints of rails?

A: While laying the railway track, a small gap is left between the two successive lengths of rails. The purpose is that the rails grow in summer. The gap is fitted to enable this extension. If no gap is left, the expansion in summer will cause the rails to bend sideways.
