S49 Rail Joint Bar For Track Fastening System

An S49 rail joint bar (also called a fishplate or splice bar) is a precisely engineered metal bar used to bolt the ends of two S49 steel rails together, ensuring structural integrity and a smooth transition for train wheels. These components are available in 4-hole or 6-hole configurations and comply with standards like DIN 5901 and EN 13674-4

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: 45# steel or 55# steel .

• Holes: 4 holes or 6 holes.

• Weight: A 4-hole S49 joint bar weighs can range from 8kg to 10kg which base on its design.

• Length: Common lengths are 580mm, 790mm or 820mm for 4-hole bars.

• Standard Compliance: EN 13674 or DIN standards. 

Where are S49 Rail Joint Bars used?

S49 rail joint bars (or fishplates) are used to connect sections of S49 rail (equivalent to European standard 49E1) across various infrastructure sectors where that specific rail profile is the standard. They are critical for ensuring continuity and stability in the track. Their primary applications include: 

1. Mainline and Freight Rail Networks

• Europe and South America: S49 rail is a common standard in many European and South American countries. The joint bars are extensively used in mainline rail networks for both long-distance passenger and heavy-haul freight services (e.g., mineral cargo, agricultural goods). 

2. Industrial and Mining Systems

• Mining Operations: Used in heavy-duty tracks within underground and surface mines to transport equipment and materials, providing a robust connection that resists high impact and abrasion.

• Industrial Plants: Employed in on-site transport systems within large industrial complexes such as steel mills, chemical plants, and manufacturing facilities.

• Port Logistics: Applied in port terminals and dry ports for rail systems used to move and stack containers. 

3. Urban Transport Infrastructure

• Light Rail and Trams: Found in some urban light rail systems and tram networks where this rail profile is utilized, helping maintain track continuity in city environments.

• Subway/Metro Systems: Used in specific subway lines that have standardized their tracks to the S49/49E1 profile. 

4. Specialized and Temporary Applications

• Temporary Tracks: Utilized by construction contractors for temporary rail setups during the construction of major infrastructure projects (e.g., tunnels, bridges) due to their reliability and ease of assembly/disassembly.

• Insulated Joints: Specialized insulated joint bars are used near signals or in electrified sections to create electrical breaks for signal systems while maintaining the mechanical connection of the rails.
