Description
Rails are the main components of railway tracks. Their function is to guide the wheels of locomotives and vehicles forward, bear the huge pressure of the wheels, and transmit it to the sleepers. Rails must provide a continuous, smooth and least resistant rolling surface for the wheels. In electrified railways or automatic block sections, rails can also be used as track circuits.
The cross-section of the rail adopts an I-shaped cross-section with the best bending resistance, which consists of three parts: the rail head, the rail waist and the rail bottom. In order to enable the rail to better withstand forces from all directions and ensure the necessary strength conditions, the rail should be of sufficient height, its head and bottom should have sufficient area and height, and the waist and bottom should not be too thin.
Chinese rails can be divided into three types: crane rails (crane rails), heavy rails and light rails according to their approximate weight in kilograms per meter.
