Rail Joint Bar for Rail S49

A rail joint bar (or fishplate) for S49 rail is a metal bar used to connect two sections of S49 steel rail, available in 4-hole or 6-hole configurations and manufactured to standards like EN 13674-4 or DIN5901.

Key Specifications

S49 rail joint bars are specifically designed to fit the profile of S49 rail, which is equivalent to the EN 49E1 standard rail, with a nominal weight of approximately 49.39 kg/m. 

• Material: Q355B,45# or 55# steel.

• Holes: Available with 4 holes or 6 holes for bolting.

• Weight: A 4-hole 580mm S49 joint bar weighs 7.85 kg, it depends on its drawing and length.

• Length: Common lengths are around 790mm or 820mm for 4-hole bars.

• Standard Compliance: Manufactured to meet relevant international standards EN 13674 or DIN standards. 

Key Functions

• A Rail Joint Bar for Rail S49 is typically used to connect two sections of S49 rails together to form a continuous rail track. 

• These joint bars are crucial for maintaining the stability of the track and ensuring that the rails are securely joined to prevent movement at the joint.

Key Applications

S49 rail joint bars (also known as fishplates) are used to connect sections of S49 rail (equivalent to European standard 49E1) across various infrastructure sectors. 

1. Mining and Industrial Rail Systems 

• Underground Mining: Used in heavy-duty tracks within mining tunnels to transport ore and equipment, providing a robust connection that resists high impact and abrasion.

• Industrial Plants: Employed in in-plant transport systems for steel mills, chemical plants, and manufacturing sites to handle oversized raw materials.

• Crane Tracks: Critical for securing segments of rails used for overhead, gantry, and stacker cranes in industrial yards. 

2. Transport Infrastructure 

• Regional Freight and Mainline Networks: Used in mainline rail networks, especially in Europe and South America, for both mineral cargo freight and long-distance passenger services.

• Urban Transit: Found in subways, tram systems, and light rail networks to maintain track continuity in city environments.

• Port Logistics: Applied in port terminals and dry ports to connect rail systems for container movers and transport wagons. 

3. Specialized and Temporary Applications

• Temporary Tracks: Utilized by infrastructure contractors for temporary setups during the construction of tunnels, bridges, or highways due to their ease of assembly and removal.

• Automated Warehouses: Used in high-precision tracks for automated shuttle systems and logistics warehouses to ensure smooth, high-speed operation.

• Insulated Joints: Specifically designed insulated joint bars are used near signals or in electrified sections to create electrical breaks while maintaining mechanical connection. 

4. Regional Usage

• Europe and Asia: Widely used in public projects where EN 49E1 or DIN 5901 standards are specified.

• South America: Noted as a key component for agricultural and mineral freight networks.
