Rail Shoulder Material Technical Parameter
Sep 15, 2025
A rail shoulder is a pre-inserted item in the concrete sleepers, no matter for single stem type or twin stem type, used to fix the elastic rail clips, mainly e-clips, within the fastening system.
We are capable of producing two types of rail shoulders for rail clips: cast in shoulder and weld-on shoulder.

Features And Advantages of GNEE rail shoulder
GNEE RAIL rail shoulders are designed to solve problems such as broken shoulders resulting from fragile material, difficulty installing, and low load transfer efficiency. Due to its outstanding features in load transfer anti-fatigue design and easy installation, the product can effectively reduce maintenance, shorten project cycles, and improve the safety and reliability of the rail system.
Premium material
Our rail shoulders adopt high-quality steel and composite materials and have gained extremely high resistance to pressure, wear, and corrosion. The product is durable and not easy to deform or crack.
Improve track stability
With the scientific design, our rail shoulder can effectively disperse the load from rails, and reduce displacement and deformation, thus keeping the stable running of trains.
Reduce maintenance costs
The rail shoulder has a long service life and low maintenance frequency, which can greatly reduce the costs resulting from frequent changes or maintenance of parts.
The function of rail shoulder
Rail shoulder is widely applied in railroad track construction and maintenance projects, especially the rail systems with high load and high speed (50kg, 85kg, 90/91LB, 115RE/136RE, UIC54 & UIC60 rail). By using the rail shoulder, the stability of the railroad track is improved, and the service life of the track is extended. Its principal function lies in the following aspects.
Supporting rails: providing stable support to prevent rails from displacement.
Transfer load: the weight applied on the railway track is evenly distributed to the ballast bed to prevent local excessive pressure.
Deformation resistance: reduce the stress caused by environmental factors such as temperature and humidity changes on the track, so as to prevent the track from deformation, fracture, and other problems.
Usage scenario
Rail shoulder is suitable for various types of rails especially the ones that are frequently used or under high load.
High-speed rails: providing stable support to prevent rails from displacement.
Urban rail transportation: the rail shoulder is conducive to increasing the durability and safety of the urban rail transportation systems such as the subway and the light rail.
Heavy-haul transportation: rail should effectively share the load from heavy-haul lines to ensure long-term stability and safety.
GNEE RAIL also offers different kinds of railway fasteners to meet client's requirements, such as Elastic Rail Clip and Clamp, Rail Screw Spike, Plastic Dowel, High Tensile Track Bolt with Nut, Rail Base(Tie) Plate, Rail Fish Plate, Fish Bolt, Railroad Rubber and EVA Pad, etc. Samples and drawings provided by customer, we will manufacture qualified products accordingly.
