A compromise rail joint is a special structural rail joint used to connect two sections of steel rails. It is designed with non-standard dimensions or special structures according to the operating conditions, rail type, and stress requirements. Usually forged or hot-rolled from high-strength carbon steel or alloy steel, the two steel rails are firmly clamped by bolts to form reliable support at the track joint.
Compared with conventional railway fishplates, their most distinctive features are: unique shapes, special structures, matching specific rail types, and being customized according to drawings and needs.
AGICO Rail supplies various types of rail joints (or railway fish plates) with different standards, including ARME, UIC, BS, etc. We also provide customized compromise joint bars according to drawings of clients.

Function of compromise rail joint
- Connect the steel rails to ensure track continuity.
- Disperse the force on the rail end and reduce the impact.
- Enhance the strength of rail joints and extend their lifespan.
- Compensate for additional stress in curved and sloping conditions.
- Used for temporary or long-term track renovation projects.
- Provide track insulation (insulated compromise fishplates).
Highlights of compromise rail joint
- Customized according to rail track type (precise matching)
Tailored rail fishplate grooves and fitting surfaces can be made according to the cross-sectional shape of the steel rail (such as 50kg, 60kg, 75kg, UIC60, AREMA 136RE, ZUI rail type).
- Higher structural strength
Usually, thickened design, reinforced rib plates, and inclined shear structures are used, with a bearing capacity 15-40% higher than ordinary railway fishplates.
- Anti fatigue design
The rail end is a high-risk area for fatigue cracks, and the reinforced fishplate with irregular shapes can effectively reduce crack propagation and improve safety.
- Multiple materials to choose from
- 45 # steel, Q235, Q275, Q355 (hot-rolled/forged)
- Alloy steel (such as 20MnTi, 35CrMo) (heavy-duty railway)
- Insulation materials (GFRP, SMC) (electrified railways, signal sections)
- High compatibility
Fully customizable according to customer drawings, compatible with various track gauges:
- 1435mm (standard rail)
- 1000mm, 1067mm (narrow gauge)
- 1676mm (wide gauge)
How to manufacture compromise rail joint?
As a high stress rail fastener, the manufacturing process of compromise rail joints is more complex than that of ordinary standard rail joint, and precise machining must be carried out according to the rail type and mechanical requirements. The following is the complete industrial production process. Accurate modeling → Professional mold → Hot forging/hot rolling → CNC precision machining → Heat treatment → Surface anti-corrosion → Full inspection.
- Firstly, we will rigorously screen and inspect the raw materials.
- The second step is to conduct track modeling and mold development, which is one of the most crucial steps in manufacturing irregular fishplates.
- The third step is to enter the hot forging or hot rolling forming stage, transforming the steel from a regular billet to the basic shape of a fishplate.
- The fourth step is to further improve dimensional accuracy and structural consistency through numerical control machining (CNC).
- Step five, we perform heat treatment on the product to obtain the required strength and toughness.
- Step six, we perform surface treatment processes to improve corrosion resistance and service life.
- The seventh and final step is to conduct a comprehensive inspection of the finished product and complete packaging and shipping.

FAQ
1. What is the difference between compromise rail joint and normal rail joint?
Ordinary rail joint are universal for standard rail types; The compromise rail joint is designed for special rail types or special stress, and belongs to customized parts.
2. I don't have any drawings, can you make them?
Sure, just provide the track type model or on-site photo measurement data, and we can reverse model.
3. Can insulated rail joint withstand high temperatures?
SMC/GFRP material can withstand temperatures up to 130-150 ° C and can be used in subway signal sections.
4. How long is the delivery time?
Standard rail type takes 15-25 days, fully customized type takes 25-35 days.
5. Can anti-corrosion treatment be done?
Can be used for shot blasting, oiling, painting, hot-dip galvanizing, etc.
