A rail fish plate is a precision-machined connector that stabilizes rail ends, controls joint geometry, and distributes wheel loads evenly across the joint section, reducing stress concentration and vibration. It is indispensable where continuous welded rail is not feasible. GNEE RAIL offers fish plates for GB light and heavy rails, UIC profiles, DIN536 crane rails, QU crane rails, JIS standard rails, AS1085 rails, BS11 sections, and AREMA/ASCE rails, with services including joint design matching and project supply management.
Weight of Railway Fish Plate
Railway fish plates, also known as splice bars, vary in weight based on rail type, ranging from approximately 5 kg to over 29 kg per plate for standard tracks, with common heavy rail (52 kg/60 kg) plates typically weighing between 15 kg and 25 kg each. These high-strength steel components are used in pairs, with 4-6 holes for bolting.
Common Fish Plate Weights by Rail Type
- Light Rail (8 kg - 30 kg): Generally lower weight, suitable for light industrial or mine tracks.
- Heavy Rail (38 kg - 75 kg): Typically weighs 15-28 kg per plate, with 60 kg rails often requiring plates around 17-25 kg each.

How to select the appropriate rail joint specifications?
Selecting appropriate rail joint specifications requires matching the joint bars to the rail profile (e.g., 60kg/m, 50kg/m, 115RE, 136RE) while ensuring they meet strict strength, stiffness, and structural integrity requirements. Key considerations include providing sufficient expansion/contraction gaps (approx. 18mm max) for temperature changes, selecting between glued (for continuous welded rail) or conventional bolted joints, and ensuring proper bolt hole alignment for uniform load distribution.

Key Factors for Selecting Rail Joint Specifications:
Rail Profile and Weight: Match the joint bar (fishplate) specifically to the rail type (e.g., 38kg, 43kg, 50kg, 60kg, 75kg for heavy rail, or specific RE sections like 115RE, 132RE, 136RE) to ensure a precise fit.
Joint Type and Functionality:
- Insulated Joints (GIRs): Essential for signaling in electrified tracks; require high-strength, insulated materials (e.g., glass fiber-reinforced epoxy).
- Glued Insulated Joints: Preferred for modern long-welded rails (CWR) to maintain insulation and strength.
- Transition/Compromise Joints: Used to connect different sizes of rail (e.g., 60kg to 50kg).
