Abstract: Railroad rails having improved wear resistance, are produced by controlled forced cooling from above the austenite transformation temperature, to produce rails having a fine pearlite metallurgical structure in the head portions of the rails. Apparatus comprising a series of cooling headers utilizing a liquid cooling medium, such as unheated (i.e., cold, or ambient temperature) water, alternating with a series of air zones, is preferably arranged in line with the production rolling mill, to receive hot rails as they emerge from the mill, without the necessity of intervening reheating. A roller type restraint system transports the rails through the cooling apparatus, while restraining them in the appropriate position.
