Heavy Rail Steel Supplier - AREMA Standard Rail 115RE 136RE for Railway Track
Heavy rail steel serves as the backbone of modern railway infrastructure, bearing the immense loads of freight trains and high-speed passenger services across thousands of miles of track. As a professional heavy rail supplier with over a decade of experience in steel product export, we provide AREMA-standard rail sections including 115RE, 136RE, and other profiles engineered for demanding mainline railway applications. Whether you are constructing new rail corridors, upgrading existing track, or sourcing replacement rail for maintenance programs, our mill-direct supply chain ensures premium-grade heavy rail delivered to your project site with full material certification and competitive pricing.
What is Heavy Rail?
Heavy rail refers to steel rail sections with a linear mass of 30 kg/m (approximately 60 lb/yd) or greater, specifically designed for mainline railway operations carrying heavy axle loads. In North American standards, heavy rail profiles such as 115RE (57.0 kg/m) and 136RE (67.5 kg/m) are manufactured to AREMA (American Railway Engineering and Maintenance-of-Way Association) specifications. These rails feature a robust head-web-base geometry optimized for fatigue resistance, wear durability, and safe wheel-rail contact under repeated loading cycles exceeding 35-ton axle loads.
Heavy Rail Technical Specifications
Our heavy rail products are manufactured from high-carbon steel with precise chemical and mechanical properties to meet rigorous railway performance standards. Below are the key specifications for our most requested profiles:
| Specification | 115RE Rail | 136RE Rail |
|---|---|---|
| Linear Mass | 57.0 kg/m (115 lb/yd) | 67.5 kg/m (136 lb/yd) |
| Rail Height | 168.3 mm (6.625 in) | 185.7 mm (7.3125 in) |
| Head Width | 69.1 mm (2.719 in) | 74.6 mm (2.938 in) |
| Base Width | 139.7 mm (5.5 in) | 152.4 mm (6.0 in) |
| Carbon Content | 0.72%–0.82% | 0.72%–0.82% |
| Minimum Tensile Strength | 880 MPa (128 ksi) | 880 MPa (128 ksi) |
| Minimum Hardness (Head) | 300 HB | 300 HB |
| Standard Length | 24.38 m (80 ft) / 25 m | 24.38 m (80 ft) / 25 m |
| Standard | AREMA | AREMA |
Additional rail grades are available, including head-hardened (HH) variants with surface hardness reaching 340–390 HB for curves and high-wear zones. All rails undergo ultrasonic testing and straightness inspection per AREMA Chapter 4 requirements before shipment.
Applications of Heavy Rail Steel in Railway Construction
Heavy rail finds extensive application across diverse railway environments where load-bearing capacity and long service life are critical. The 136RE profile is the standard choice for Class I freight railroads in North America, supporting gross rail loads exceeding 315,000 lbs per car. The 115RE section serves branch lines, industrial sidings, and transit systems where moderate traffic density allows a lighter rail profile without compromising safety. Beyond conventional railways, heavy rail sections are also specified for port rail infrastructure, mining haul roads, and heavy-duty crane runways where repeated high-impact loading demands superior fatigue performance.
