What is 136 re rail?
136RE rail, also written as AREMA 136RE rail, 136 RE steel rail, or 136 pound rail, is a standard heavy rail defined by AREMA (American Railway Engineering and Maintenance-of-Way Association). The "136" refers to its weight of 136 lb per yard (≈67.5 kg/m), making it a widely used heavy rail for high-load railway systems.
The typical 136RE rail profile includes a height of about 185.7 mm, head width of 74.6 mm, and base width of 152.4 mm. This optimized 136RE rail section provides high strength, excellent wear resistance, and stable performance under heavy axle loads.

136RE Rail Section & Structural Advantages
The 136RE rail section is designed for optimal load distribution and structural performance. This is critical in heavy-haul and high-traffic railways.
- Superior Load-Bearing & Stiffness: The optimized, taller profile (185.74mm) ensures excellent vertical and lateral stiffness, significantly reducing deformation and stress under heavy axle loads, making it ideal for high-capacity freight lines.
- Improved Wear Resistance: The wider, robust rail head (74.61mm) offers a larger contact surface area, which helps disperse wheel pressure, reducing fatigue and wear in high-traffic or high-curvature areas.
- High-Quality Steel Formulation: Manufactured with high-strength, wear-resistant, and corrosion-resistant steel, 136RE rails are designed for long-term service in harsh, intense industrial environments.
- Compatibility & Stability: As a standard AREMA profile, 136RE is easily integrated into existing North American railroad infrastructures. It is often used in place of 115RE or 132RE in lines requiring higher structural performance.
- Lower Maintenance Costs: The increased durability, high-strength material, and stable design result in reduced maintenance frequency, lower risk of fatigue cracks, and prolonged rail life.
136RE rails are commonly utilized on major freight routes, in mining and quarry transportation, and as high-capacity tracks for heavy industrial overhead cranes.
