A rail fish plate is a mechanical coupling bar that ensures alignment and load cooperation between adjoining rail lengths by binding their webs with high-strength bolts. GNEE RAIL supplies fish plates matched to GB light and heavy rails, UIC standard rails, DIN536 and QU crane rail applications, JIS rail profiles, AS1085 sections, BS11 rails, and AREMA/ASCE standards, supported by dimensional inspection services.

What are the different types of rail joints?
Rail joints are essential structural connections that bridge adjacent rails, classified by sleeper position, joint placement, or function. Major types include supported, suspended, and bridge joints based on support; staggered or squared based on position; and specialized insulated or compromise joints for electrical isolation or connecting different rail profiles.
| Joint Type | Key Specification / Description |
| Standard Rail Joint (Fish Plate) | - Profile: Matches the rail section (e.g., UIC 60, 136RE). |
| - Length: Typically 600mm or 800mm per side. | |
| - Holes: 4 or 6 bolt holes per bar. | |
| Insulated Rail Joint (IRJ) | - Material: Steel core with composite insulating end-posts/plates, or full epoxy composite. |
| - Electrical Resistance: >10⁸ Ω. | |
| Compromise Rail Joint | - Design: Connects two different rail profiles (e.g., UIC 54 to UIC 60). |
| - Profile: Each side is machined to match its respective rail section. | |
| Joggled Rail Joint | - Feature: Has a depressed (joggled) section to allow continuous rail head surface for smoother wheel passage. |
| Bridge Rail Joint | - Design: Often reinforced (thicker web/longer length) for high-stress locations like bridge approaches. |
| Glued Insulated Joint | - Construction: Steel bars bonded to composite insulation using high-strength adhesive for improved durability. |
| Welded Rail Joint (for CWR) | - Type: Flash-butt or thermite weld. |
| - Specification: Weld must meet mechanical properties equal to or greater than the parent rail. | |
| Expansion Joint (for BRE) | - Feature: Allows controlled thermal expansion in long rails on bridges or in extreme temperature zones. |
How much does a joggled fish plate weight in kg?
A joggled fish plate typically weighs between 12 kg and 17.5 kg per piece, depending on the rail profile (e.g., 52 kg or 60 kg) and length. Common 4-hole or 6-hole joggled fish plates used for rapid repair generally fall within the 12–15 kg range, with 52 kg variants often weighing approximately 16.97–17.38 kg.
- 52 kg Joggled Fish Plate: Approx. 12–17.4 kg per piece.
- 60 kg Joggled Fish Plate: Approx. 12–15 kg per piece.
- Common Lengths: Usually around 600 mm to 685 mm.
- Material: Typically hot-rolled carbon or alloy steel.
These plates are designed for quick installation on railways, often used in pairs.
What are the advantages of using a joggled rail joint?
Joggled rail joints (using joggled fish plates) provide a highly stable, durable, and cost-effective solution for repairing, maintaining, and connecting railway tracks, especially in emergencies. Their primary advantages include enhanced safety by preventing derailments, superior durability against wear, and the ability to accommodate welded joints or different rail sections securely.
Key Advantages of Joggled Rail Joints:
- Emergency Repair & Safety: Joggled fish plates are specifically designed to quickly repair cracked rails or broken joints. They are used in conjunction with clamp assemblies to maintain track safety and allow train movement, often at restricted speeds, until permanent repairs can be made.
- Enhanced Stability & Support: Due to their specialized shape, these plates provide increased stability to rail joints, reducing the risk of misalignment and ensuring better structural integrity.
- Durability and Wear Resistance: These joints are designed to handle heavy loads and possess high resistance to rust, wear, and tear, leading to a longer service life compared to standard joints.
- Protection of Welded Joints: They are frequently used to protect newly welded joints, particularly when accommodating different rail sections (e.g., 60 kg to 52 kg rail) or covering weld collars, providing a safe, temporary solution until the joints can be properly tested.
- Cost-Effective Maintenance: By providing robust support, they reduce the frequency of maintenance and the need for immediate, full-section replacements.
