A rail fish plate is a mechanical joint reinforcement component that compensates for the loss of beam continuity at rail discontinuities by clamping adjacent rail webs into a unified load-carrying section. Without fish plates, jointed rail cannot safely withstand repeated axle loads.
GNEE RAILWAY RAILWAY provides fish plates for GB light rail and heavy rail, UIC standard rails, DIN536 and QU crane rails, JIS rail types, AS1085 sections, BS11 profiles, and AREMA/ASCE standards, and supports customers with rail–joint compatibility verification and bulk supply coordination.
Specifications of Various Standards of Railway Fish Plate
Railway fish plates (joint bars) are critical, high-strength steel connectors, typically conforming to standards like AREMA, UIC, or GOST, used to securely fasten rail ends. They are available in 4-hole or 6-hole configurations, matching specific rail weights (e.g., 60 kg, 52 kg, UIC 60, 115RE, 132RE) to ensure structural stability and load transfer.

Types of fish plate in railway
Railway fish plates (joint bars) connect rail ends to ensure structural continuity, commonly categorized by rail weight (light, heavy, crane), function, and bolt hole configuration (4 or 6 holes). Key types include standard, insulated, compromise, and joggled fish plates, tailored for different, speeds, and loads.
| 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. |
