A rail fish plate is a steel joint component designed to restore bending stiffness and alignment continuity at rail ends, enabling smooth wheel passage while maintaining structural integrity of the track. Without proper fish plates, joint areas become high-stress failure points. GNEE RAIL provides fish plates for GB 8–60 kg/m rails, UIC50–UIC60, DIN536 crane rails, QU70–QU120, JIS standard rails, AS1085 profiles, BS11 sections, and AREMA/ASCE rails, with machining accuracy control and quality inspection services.
What are the different types of rail joint bars?
Rail joint bars, also known as fishplates or splice bars, are designed to connect rail ends, ensuring track continuity and stability. The main types include common/standard (for same-sized rails), compromise (for different rail sizes), insulated (for electrical insulation), joggled (for emergency repair), and expansion (for thermal movement) joints. They are classified by hole count (4 or 6), weight (light, heavy, or crane), and standard (e.g., UIC, AREMA).
Key types of rail joint bars include:
- Common Joint Bars (Fishplates): The most common type, used to connect rails of the same size. These typically feature 4 or 6 bolt holes and are designed for standard trackage.
- Compromise Joint Bars: These are specially designed/forged to join rails of different profiles, heights, or sizes, allowing for a smooth transition, often used in switches.
- Insulated Joint Bars: Used in electrified, signaled tracks to prevent current flow between rails. They are made from high-strength insulating materials (e.g., polyurethane or nylon-coated steel) and are crucial for signaling systems.
- Joggled/Bulge Rail Joints: Specifically designed to join broken or cracked rails on a temporary basis, these offer a secure fit, often used with emergency clamps.
- Expansion Joint Bars (Expansion Devices): Used at locations with high temperature variations to allow for, or control, the expansion and contraction of rail tracks.
- Glued Insulated Joints: A type of insulated joint where the bars are glued to the rails, providing higher strength, better insulation, and increased resistance to longitudinal forces.
Rail Fish Plate Dimensions
Used as an emergency clamp, joggled fish plate enables quick and temporary repair, allowing continued movements through the section at a reduced line speed.
