A P65 rail fishplate, also known as a rail joint bar, is a critical component in railway infrastructure, used to connect two steel rail sections securely. The fishplate ensures the stability and continuity of railway tracks, reducing the impact of dynamic loads and improving safety.

The P65 rail fishplate is specifically designed for the P65 rail type, which is widely used in heavy-load railway tracks, including freight and passenger rail systems. Manufactured from high-strength steel, the fishplate provides excellent durability and resistance to wear and tear.

Structural Connection – The primary function of the fishplate is to connect two rail ends, ensuring seamless track continuity.

Load Distribution – By maintaining the alignment of the rails, the fishplate evenly distributes the stress and load exerted by passing trains.

Track Safety – Properly installed fishplates help minimize rail displacement, reducing derailment risks.

Shock Absorption – They aid in reducing vibration and impact, which prolongs the life of the rails and fasteners.

Material: High-quality carbon steel or alloy steel.

Length: Typically ranges between 600mm to 900mm.

Thickness: Around 30mm to 50mm, depending on design requirements.

Hole Configuration: Typically consists of 4 or 6 bolt holes to secure the plate firmly onto the rail.

Weight: Approximately 18-22 kg per piece, based on the exact dimensions.

Raw Material Selection – High-grade steel is chosen to meet railway standards.

Cutting & Shaping – The steel is cut and shaped into the precise fishplate dimensions.

Drilling & Machining – Bolt holes are drilled accurately to align with rail fasteners.

Heat Treatment – Enhances the fishplate's durability and resistance to mechanical stress.

Surface Treatment – Anti-corrosion coatings such as zinc plating or oiling are applied.

Aligning the Rail Ends – Ensure that the two rail ends are properly positioned.

Placing the Fishplate – Position the fishplate against the sides of the rail.

Bolting Securely – Insert bolts through the drilled holes and tighten them firmly.

Inspection – Check for proper alignment and stability.

Advantages of P65 Rail Fishplate

Cost-Effective – Less expensive compared to welded joints.

Easy Installation & Maintenance – Quick to install or replace without specialized equipment.

High Strength & Durability – Provides long-lasting performance under heavy loads.

Flexibility – Allows for rail expansion and contraction due to temperature variations.

The P65 rail fishplate plays an essential role in railway track connectivity and safety. Its robust design and ability to handle heavy loads make it an indispensable component for railway construction and maintenance. By ensuring proper installation and periodic maintenance, rail operators can enhance the lifespan of their tracks and ensure smooth train operations.
