How Heavy Is A Rail

Aug 15, 2025 Leave a message

Steel Rails are the key parts of the rail track laid in two parallel lines to provide a continuous, steady and level surface for the runnings of trains.

With increasing train weights and speeds, the requirements for rail stress resistance have intensified. Consequently, GNEE RAIL employs high-carbon steel for rail production (carbon content: 0.6% to 0.8%, manganese: 0.8% to 1.3%, silicon: 0.1% to 0.5%, sulfur and phosphorus each ≤0.03%, aluminum ≤0.015%). Under harsh conditions, rails must utilize corrosion-resistant steel, for which GNEE has developed multiple proprietary formulations.

Rail weights are categorized into heavy rails and light rails based on type, as detailed below:

Light rails: Weight per meter less than 30 kg. Common specifications include No. 5, No. 8, No. 11, No. 15, No. 18, and No. 24, with weights ranging from 6.41 kg/m to 31.24 kg/m.

Heavy rails: Nominal weight per meter exceeding 30 kg. Common specifications encompass 38 kg/m, 43 kg/m, 50 kg/m, and 60 kg/m, with weights spanning 49.5 kg/m to 65.8 kg/m.

Standard rail lengths: Typically 12.50 meters and 25.00 meters. Slightly shorter lengths are utilized when laying curve rails.
