W300-1 Type Railway Fastening System for High Speed Railway Track Construction

Our W300-1 Type Rail Fastening System is a high-performance integrated fastening solution specially developed for high-speed railway tracks. This complete set of track fasteners features stable structure, excellent insulation, strong fatigue resistance and convenient installation & adjustment.

The system supports precise rail gauge and rail height adjustment, requires no regular maintenance after installation, and adapts to multiple line sections including ordinary tracks, bridge sections and insulated joints. All components are manufactured in strict accordance with industry technical standards, ensuring long-term reliable operation under complex track operating conditions.

In high-speed railway operation, traditional track fasteners often face multiple challenges: unstable fastening force leading to rail displacement, limited adjustment range unable to adapt to track elevation and gauge deviation, poor fatigue resistance causing early component damage, complicated daily maintenance increasing operation costs, and insufficient insulation performance affecting signal system stability.

Different track sections such as bridges and insulated joints have differentiated requirements for fastener longitudinal resistance, while most ordinary fasteners cannot meet multi-scene matching demands.

The W300-1 Type Rail Fastening System perfectly solves the above problems with integrated design and standardized components. We equip multiple types of elastic clips, gage baffles and tie plates to realize ±16mm rail gauge adjustment and -4mm to +56mm rail height adjustment.

Different elastic clip models are configured for ordinary sections, low-resistance bridge sections and insulated joints separately to match different longitudinal resistance demands. The whole system adopts high-strength raw materials, with outstanding fatigue resistance and insulation performance. It realizes one-time installation without regular tightening and maintenance, greatly reducing track later operation and maintenance workload.

• High-speed Main Lines: The core application scenario, suitable for conventional sections of high-speed railways, stable fastening ensures safe operation of high-speed trains.
• Bridge & Viaduct Sections: Equipped with low-resistance elastic clips to reduce longitudinal resistance, adapt to the stress characteristics of bridge tracks.
• Rail Insulated Joints: Matched with special insulated elastic clips and gaskets to guarantee track insulation and normal work of railway signal system.
• Track Renovation & Maintenance: Support precise rail height and gauge adjustment, ideal for track deviation correction and old line renovation projects.
• Concrete Sleeper / Track Slab Tracks: Compatible with precast concrete sleepers and track slabs, widely used in ballastless track engineering.

The W300-1 fastening system adopts a layered assembly structure. Firstly, the elastic pad is laid on the sleeper bearing surface to buffer track vibration, then the steel tie plate and rail pad are placed in sequence to disperse wheel load.

The gauge baffles are installed on both sides of the rail to limit lateral displacement of the rail and realize rail gauge adjustment by replacing baffles of different specifications. The elastic clip is fixed by screw spikes embedded in the sleeper sleeve, relying on the elastic tension of the clip arm to compress the rail stably.

Insulation gaskets are installed between the clip and rail bottom to ensure electrical insulation of the track. For rail height adjustment, combine rail pads, plastic and steel heightening pads of different thicknesses, and match screw spikes of corresponding lengths to complete height calibration. After installation, the elastic clip maintains continuous fastening force without repeated tightening.

• Select Elastic Clip by Track Section: Choose SKL15 for ordinary track sections; select SKL B15 or SKL15LT for bridges and low-resistance sections; use SKL15IF for rail insulated joints, and match the corresponding insulating gaskets.
• Select Gauge Baffle by Deviation: Calculate the actual rail gauge deviation, select Wfp15a / Wfp15u series baffles with ±1 ~ ±8 models according to the ±16mm adjustment range.
• Select Heightening Accessories by Rail Height Deviation: Within -4mm ~ +2mm, only replace rail pads of different thicknesses; +3mm ~ +28mm use plastic heightening pads combined with rail pads; +29mm ~ +56mm add steel heightening pads, and select matched length screw spikes.
• Installation Demand: The whole set supports pre-installation in factory and on-site final installation, compatible with manual wrenches and electric bolt tightening equipment.

A: No. The W300-1 fastening system is designed for maintenance-free use after installation. The elastic clip can maintain permanent fastening force, and there is no need to regularly retighten screw spikes. Daily inspection only needs to check component integrity and track geometric parameters.

A: The rail gauge can be adjusted within ±16mm, with 1mm for each adjustment step. The rail height adjustment range is -4mm to +56mm, which can meet the demands of track construction, renovation and maintenance in most scenarios.

A: Yes. The system is specially designed for high-speed railway ballastless tracks, perfectly matching concrete sleepers and track slabs. The embedded sleeve has strict installation precision requirements, and the overall structure fits well with ballastless track structures.

A: Common manual sleeve wrenches, single-head/double-head electric wrenches and four-head electric bolt machines are all applicable. No special large-scale mechanical equipment is required, and both factory pre-installation and on-site rapid construction can be realized.

A: All parts are made of high-strength anti-fatigue and anti-corrosion materials. After strict fatigue test and salt spray test, the components can operate stably for a long time in outdoor complex environments, with excellent anti-aging and anti-damage performance.
