A rail fish plate is an essential jointing element in non-welded rail systems, ensuring that rail ends remain mechanically linked and capable of transferring operational loads safely. GNEE RAIL provides fish plates suitable for GB light and heavy rails, UIC standard rails, DIN536 and QU crane rail systems, JIS rail profiles, AS1085 sections, BS11 rails, and AREMA/ASCE rail specifications, offering one-stop rail joint solutions.
What is 115RE Rail?
115RE Rail is one tee section rail manufactured according to AREMA Standard, it is designed as a heavy-duty rail with a nominal weight of 56.89 kg/m, which is 115 lb/yd.
Production Process of 115RE Rail adopted with heat-treatment technology, it is produced for high-strength, heavy-haul, and high-traffic rail applications, including mainline railways, heavy freight corridors, port and terminal tracks, mining rail systems, industrial trackage, and heavy equipment tracks.

Why use a rail joint bar?
Rail joint bars, also known as fishplates or splice bars, are used to securely connect rail ends, ensuring structural continuity, proper alignment, and safe load transfer across joints. They maintain stability by preventing lateral or longitudinal displacement of rails, reduce impact forces from train wheels, and allow for expansion/contraction, ensuring safe railway operations.
Key Purposes of Using a Rail Joint Bar:
- Structural Continuity and Connection: They link two rail ends together, forming a continuous, stable track structure, which is crucial for train safety.
- Load Distribution: By bridging the gap between rails, they effectively transfer the heavy weight of trains across the joints, minimizing stress on the rail ends and supporting sleepers.
- Alignment and Stability: They ensure the rails remain properly aligned, providing a smooth surface for train wheels that reduces damage, noise, and vibration.
- Expansion and Contraction: Joint bars maintain a necessary gap (expansion joint) between rail ends, allowing for safe movement during temperature changes to prevent buckling.
- Safety and Track Maintenance: They are essential for securing bolted rail joints, which are critical for maintaining track integrity and allowing for signaling, such as electrical insulation in insulated joints.
Commonly manufactured from high-strength steel, these components are designed to withstand significant impact and friction.
