A rail fish plate is a structural connector designed to maintain alignment and stiffness at rail joints, ensuring that rail ends act together under vertical and lateral forces rather than behaving independently. GNEE RAIL provides fish plates compatible with GB 8–60 kg/m, UIC50–UIC60, DIN536 A-series, QU crane rails, JIS standards, AS1085 rails, BS11 profiles, and AREMA/ASCE rails, along with bolt and washer supply.
What is a joggled fish plate?
A joggled fish plate is a specialized, forged steel rail connector featuring a convex, bent, or "joggled" center section designed to fit over weld collars. Used primarily for emergency repairs of broken or fractured welds, these plates allow trains to pass safely at reduced speeds without immediate re-welding.
Key Aspects of Joggled Fish Plates:
- Purpose: They provide quick, temporary, and strong support to broken welded joints, fractured rails, or misaligned sections.
- Design: They have a built-in bulge or bend, which allows them to accommodate the weld collar at the joint, unlike standard flat fish plates.
- Installation: Often used in conjunction with "C" type clamps, they can be secured tightly to the rail without requiring the drilling of new bolt holes.
- Use Cases: Essential for repairing broken rail welds, protecting new welds before ultrasonic testing, and joining different rail sections.
How much does a 52 kg joggled fish plate weight in kg?
The joggled fishplate serves as a critical emergency repair component in railway maintenance. Primarily used to reconnect broken or fractured sections of welded rail, it provides a fast and reliable temporary solution for both matching and mismatched rail profiles. Its forged and machined design ensures sufficient strength to restore track continuity, allowing train operations to resume at reduced speeds until a permanent repair can be made. This makes it especially valuable for addressing rail fractures, defective welded joints, and other urgent track failures with minimal service disruption.

Joggled fish plate vs Comparison rail joint
Joggled fish plates and compromise (comparison) rail joints serve distinct purposes in railway engineering. Joggled plates are specialized for temporary repairs of broken welds, featuring a "bulge" to clear weld collars. Conversely, compromise joints connect rails of different sizes or profiles using custom-matched, non-standard fish plates.
Key Differences:
- Function: Joggled plates are for emergency repairs/welded joints. Compromise joints join different-sized rails.
- Design: Joggled plates have a central, forged bulge or "joggle" to accommodate weld flash or broken rail gaps. Compromise plates are shaped to transition between two different rail profiles.
- Usage: Joggled plates often act as a temporary fix to manage joint misalignment or weld defects. Compromise plates are often permanent installations for transitioning track sizes (e.g., from 60kg to 52kg rail).

Joggled Fish Plate | Compromise Rail Joint |
|---|---|---|
| Primary Purpose | Emergency repair of broken welds/rails | Connecting different rail profiles/sizes |
| Key Feature | Central bulge/curvature (joggle) | Specially shaped for mismatched heights/widths |
| Typical Location | Welded track sections, emergency repairs | Transition zones between different rail types |
| Speed Restriction | Often requires reduced speed | Depends on joint design/quality |
