7-3/4" x 11" Railroad Tie Plate

The 7-3/4" x 11" rail tie plate is a standard AREMA Plan 4 component specifically engineered for rails with a 5-1/2" base width, such as the 115RE, 119RE, and 127RE sections. 

Technical Specifications

• Dimensions: Exactly 7-3/4 inches wide by 11 inches long.

• Weight: Standard finished weight is approximately 14.09 lbs (6.4 kg) per plate.

• Shoulder Design: Typically features a double shoulder to snugly fit the rail base, providing lateral stability and preventing rail movement.

• Cant (Inclination): Includes a standard 1:40 inward cant, which tilts the rail toward the track center to ensure uniform wear on the rail head and improve stability.

• Punching Pattern: Usually follows Punch B, featuring square holes (typically 23/32" or 3/4") for standard railroad spikes.

Material and Manufacturing

• Steel Grades: Available in low-carbon steel (0.15%–0.35% Carbon, such as AISI 1020/1030) or high-carbon steel (0.35%–0.85% Carbon, such as AISI 1045/1060).

• Process: Manufactured using hot-rolling, shearing, and punching methods to ensure a uniform bearing surface.

• Surface Treatment: Often finished with black coating or hot-dip galvanization for corrosion resistance.

Common Applications

• Industrial Sidings: Frequently used for in-plant tracks and industrial spurs because the 11" length offers significant cost savings compared to longer mainline plates.

• Transit Systems: A primary choice for light rail and municipal transit systems where 115RE rail is the standard.

• Load Distribution: These plates are essential for protecting wooden ties from "cutting" or crushing by distributing heavy axle loads over a larger surface area.

Signum specializes in AREMA tie plates, specifically for 115RE or 136RE rail sections. We currently support North American infrastructure projects by providing forged,rolled and cast plates that meet Plan 8 and Plan 12 specifications.We’d love to send over our latest technical data sheets and lead times for your maintenance cycle if you need.
