Rail Tie for Rail P65 | Railway Fasteners

A rail tie(also known as rail fish plate) for P65 rail is a metal joint bar used to connect two sections of P65 rail, available in both 4-hole and 6-hole configurations and typically made from high-strength 50# or 55# carbon/alloy steel. 

Specifications

• Function: Connects two adjacent rail sections to maintain proper alignment and smooth operation of trains, bearing impact forces and restricting rail movement.

• Rail Standard: Designed for P65 (also known as R65) rail, which has a weight of approximately 64.88 kg per meter and conforms to standards GOST P51685-2022.

• Material Options: Commonly manufactured from high-strength carbon or alloy steel, such as 50# or 55# steel. Other options like 45# high carbon steel and 50Mn alloy steel are also used depending on the application.

• Holes: Typically comes with either 4 holes or 6 holes for bolting the rails together.

• Standards: Manufactured to various international standards, including TB/T 2345-2008 and GOST standards.

• Bolts: Requires high-strength fish bolts (often grade 8.8 or 10.9) to secure the joint.

Where are Rail Ties for Rail P65 used?

P65 rail ties (also known as R65 fish plates,R65 rail joint bars) are heavy-duty connectors specifically used in railway systems that follow Russian GOST standards. They are primarily found in the following environments: 

1. Geographic Regions

• These joint bars are most common in Russia, Ukraine, and other CIS/Eurasian countries. Due to global trade, they are also exported for specific infrastructure projects in Southeast Asia, South America, and Africa where heavy-haul standards are required. 

2. Mainline & High-Speed Railways

P65 is a standard for heavy-duty mainline railways. Joint bars are used to: 

• Connect 12.5m or 25m rail sections where continuous welding is not used.

• Provide structural support for tracks handling high-speed transportation and axle loads exceeding 25–30 tons. 

3. Industrial & Heavy-Haul Freight

Because P65 rail is designed for extreme durability, its joint bars are used in: 

• Mining Corridors: For coal, iron ore, and mineral transport where tracks face severe abrasion and high rolling stresses.

• Heavy Industry: Within steel mills and power plants for transporting heavy slabs and billets.

• Ports & Logistics: In container yards and multimodal transshipment areas that require high-frequency braking and load resistance. 

4. Specialized Track Sections

Joint bars are essential in specific locations where standard welding is impractical: 

• Turnouts & Switches: Connecting mainline tracks to sidings or switches.

• Insulated Joints: Special "insulated" P65 bars are used to create electrical breaks for signaling systems and traffic control.

• Temporary Repairs: For quick fixes or maintenance in remote areas until permanent welding can be performed.
