ASCE 85 rail is a heavy-duty, large-section steel rail designed for demanding railway track systems transporting heavy goods and high-speed trains. Compared to the ASCE 60 rail, ASCE 85 features a larger cross-section, with a height of 131.76 mm and a head width of 65.09 mm, making it ideal for heavy rail applications requiring exceptional strength and durability.
As the heaviest rail in the ASCE series, ASCE 85 rail weighs 42.3 kg/m and is engineered for high-demand, compact track systems. It is widely used in underground mining, heavy industry, and intermodal terminals. Made from premium U71Mn steel and meeting ASTM standards, ASCE 85 offers outstanding load capacity, superior fatigue resistance, and minimal deformation during prolonged heavy use. Its strong profile makes it the go-to choice when space is limited but maximum strength and reliability are essential for long-term performance.
Below are the detailed ASCE 85 rail dimensions and weight specifications, compliant with ASTM standards. Our ASCE 85 rails are manufactured to strict tolerances to ensure seamless compatibility with global railway systems. Custom lengths and drilling for fishplate connections are available to meet your specific project needs.
