Railroad rail, also known as the railroad track or railway track, is the main part of a railroad. Its function is to provide a continuous, smooth and least resistance rolling surface for the trains to move forward. Most modern railways use the continuous welded track (CWR) to make trains travel faster with less friction. The railroad rail is bearing great pressure when trains passing by. The pressure is transferred to the sleeper, ballast, and underlying subgrade. Railway fasteners keep rails in its place to make a safe running. Railroad rails are applied in high-speed tracks, light transport, heavy load tracks, trams, subway, factories, mining tracks, hauling tracks in forested areas, and other industrial fields. In the electrified railway or automatic block section, the rail can also be used as a track circuit.
Chemical Composition of Rails
The strength, abrasion resistance and impact resistance of the rail, to a certain extent, depending on the material of the rail. In addition to iron, the chemical composition also contains carbon, manganese, silicon, sulfur, and phosphorus. Increasing the content of carbon, manganese, and silicon can improve the strength, hardness, and toughness of the rail. But too high carbon content will reduce its plasticity and impact toughness. Proper chemical composition is the guarantee of rail quality.
Railroad Rail Dimensions and Weight
Rails are generally classified by weight over a standard length. Canada, the United Kingdom and the United States use pounds per yard. China, Australia and mainland Europe use kilograms per meter. Normally, the heavier rail supports greater axle loads and higher train speeds.
Railroad rail dimensions define the specification of the rail profile ( cross-section ). The “I-beam” section is composed of the head, height, web, and the base.

International Rail Standards
Each country in the world has its standards for the production of rails, and the classification methods are not the same. In China, railroad rail is typed into light rail, heavy rail and crane rail according to the weight of kg per meter. We have Chinese GB Standard Rails and QU Crane Rails for sale. We also have a large inventory of other types of rails to meet your requirements. Such as our hot sale products ASCE Rail, 115RE Rail, UIC60 Rail, DIN536 rail, Crane Rail, Used Rail.
AGICO products fully cover the range of international rail standards
Defined standards for light rail, heavy rail and crane rail for railways in China. The light rail is less than or equal to 30kg/m. The heavy rail is more than 30kg/m.
The European rail standard specifies that the technical conditions are applicable at the high-speed railway.
British Standards (BS) are the standards produced by the BSI group.
BS11 organized specifications and Sections of flat-bottom railway rails.
The American Railway Engineering and Maintenance-of-Way Association (AREMA) formulates the standard of rails used in the American railway.
