Heavy-Haul & Freight Railway Track & Fastening Solutions
GNEE RAIL supplies railway track and fastening components for heavy-haul freight corridors, mineral transport lines, and industrial railway systems.
Higher axle loads and frequent train movements place greater demands on rail fasteners, rail support components, and rail joints. GNEE RAIL supplies elastic rail clips, tie plates, rail pads, track bolts, fishplates, and related components according to the rail profile, sleeper type, fastening arrangement, axle-load requirements, and project specifications.
Operating Requirements For Heavy-Haul Freight Tracks
Heavy-haul and freight railway systems are exposed to repeated loading, vibration, and lateral forces. Component selection therefore depends on the rail section, track structure, fastening arrangement, and operating conditions.
Repeated Vertical Loading
Higher axle loads increase the load transferred from the rail to the fastening system, sleepers, and ballast. Rail support components are selected according to the track design and load distribution requirements.
Fastening Clamping Force
Repeated train loading and vibration affect rail restraint. Clip geometry, shoulder design, and fastening configuration are selected to provide the required clamping force for the track system.
Lateral Rail Forces
Curves and other operating conditions generate lateral forces on the rail. Tie plates, shoulders, and other fastening components provide the required lateral restraint.
Vibration and Impact
Rail pads form a resilient layer between the rail and sleeper or baseplate. Their stiffness and material are selected according to the required track performance.
Heavy-Haul Track Component Packages
GNEE RAIL supplies complete fastening assemblies and individual components for new track construction, maintenance, and replacement projects.
Elastic Rail Clips
Elastic clips provide the vertical restraint between the rail and the supporting structure. Spring steel grades such as 60Si2Mn and 51CrV4 can be used according to the required clip design and specification.
• Available Types: e-Clip series, including e1809, e2001, and e2007; SKL series, including SKL12 and SKL14; and custom clip designs.
• Clamping Force: Clip geometry and heat treatment are selected according to the required installation and clamping conditions.
Baseplates & Tie Plates
Baseplates and tie plates distribute rail loads over the sleeper or supporting structure and provide the required rail seat geometry.
Available configurations can include:
• Forged or rolled steel plates
• Ductile iron plates such as QT450-10 and QT500-7
• Pre-drilled spike or bolt holes
• Inclined rail seats such as 1:20 or 1:40
• Integrated or separate rail shoulders
The plate design is matched to the rail section, sleeper type, fastening arrangement, and project drawing.
Rail Pads
Rail pads are installed between the rail and sleeper or baseplate to provide a resilient interface within the fastening system.
Depending on the application, pad materials may include EVA, HDPE, natural rubber, TPU, or other specified materials.
Pad selection can consider:
• Required stiffness
• Dynamic loading conditions
• Rail and sleeper arrangement
• Environmental temperature
• Oil, grease, moisture, and UV exposure
• Electrical insulation requirements
The final material and performance requirements are confirmed according to the project specification.
Fishplates & Track Bolts
Fishplates and track bolts connect rail sections and maintain the required joint configuration.
Fishplates
4-hole and 6-hole configurations are available for rail sections including 115RE, 132RE, 136RE, UIC60, and 60E1, subject to the applicable drawing or standard.
Bolts & Nuts
Track bolts and nuts are available in specified strength grades, including Grade 8.8 and 10.9 configurations where required.
Joint Configuration
Hole spacing, fishplate profile, bolt diameter, and joint geometry are matched to the rail section and approved specification.
Technical Specifications & Standard Matching
Heavy-haul components are selected and manufactured according to the applicable rail profile, product standard, customer drawing, and project requirements.

Quality Control & Heavy-Haul Testing
Testing and inspection requirements depend on the component type, applicable standard, and customer specification. Available inspection items may include:
Fatigue Testing
Elastic clips can be evaluated through specified dynamic fatigue tests, including test programs of up to 3–5 million cycles where required.
01
Toe Load & Clamping Force Testing
Checks the clamping force produced by the clip under the specified installation conditions.
02
Pull-Out & Lateral Resistance Testing
Applicable to fastening components such as anchor bolts and shoulders where resistance testing is required.
03
Material Verification
Chemical composition, mechanical properties, hardness, and material traceability can be checked according to the applicable specification.
04
Material Documentation
EN 10204 3.1 Material Test Certificates (MTC) can be provided where required, including heat number and relevant material test results.
