A rail fish plate is a joint bar whose function is to prevent rail-end separation and excessive deflection by securely connecting adjoining rails under dynamic loads. GNEE RAIL supplies fish plates covering GB light and heavy rails, UIC50–UIC60, JIS rail types, AS1085 profiles, BS11 rails, AREMA/ASCE standards, and crane rail applications in DIN536 and QU systems, along with export-ready packaging.
What is a compromise joint bar?
A compromise joint bar is a specialized, non-standard railway fishplate used to connect two rails of different profiles, sizes, or wear levels. They ensure the rail head and gauge line align, enabling smooth train passage while managing stress between varying rail sections.
Key Features and Details:
- Design: These are manufactured as a pair, usually consisting of an outside and inside bar designed to fit specific, differing rail sizes (e.g., 60 lb to 85 lb or 85 lb to 115 lb).
- Purpose: They are crucial for connecting different rail sections in rail yards, switches, and during maintenance, ensuring the top of the rail surface and gauge face are aligned.
- Structure: They often feature a "bridged" or angled shape to transition between rail heights.
- Installation: They are generally sold in sets (often with alternating round and oval holes) and are critical in maintaining the structural integrity of the track at a junction.
- Maintenance: While they are essential, they are often considered a weak point in the track and may have a shorter service life compared to standard joints.
119RE compromise joint bar
The 119RE compromise joint bar is a specialized structural element designed for use in railway applications, particularly for the connection and support of rails. This joint bar is engineered to provide a robust and reliable means of joining two sections of rail, ensuring the integrity and safety of rail operations.
What are the advantages of using the 119RE compromise joint bar?
The 119RE compromise joint bar, typically used to connect 115RE and 119RE rail profiles, provides a smooth, structurally sound transition between different rail sizes. Key advantages include reducing wheel-rail impact, minimizing vibration, allowing for cost-effective maintenance, and ensuring consistent, safe alignment for heavy-duty applications.
Key advantages of the 119RE compromise joint bar include:
- Seamless Transition: It compensates for varying head heights and web thicknesses, enabling a precise fit between dissimilar rail types (e.g., 115RE and 119RE).
- Reduced Impact and Wear: By designing the joint to be smooth, it minimizes impact and vibrations as wheels pass, which reduces wear and tear on the rail, joint bars, and track bed.
- Improved Structural Integrity: Designed to handle heavy loads, these bars maintain proper alignment and strength, preventing issues associated with connecting different rail sizes.
- Cost-Effective Repairs: These bars allow for the replacement of specific, worn rail sections without needing to replace the entire track section, reducing maintenance costs.
- Versatile Design: Available in various configurations, including 4 or 6-hole, and in both standard and insulated types to fit specific operational requirements.
- High Durability: Often produced by hot rolling or forging, they provide high tensile strength and fatigue resistance, essential for heavy-duty railways and mining lines.
