Secondary title: Rail, key element in the railway superstructure
Secondary abstract: A rail is an important and the most heavily laden element in the railway superstructure, because it functions as both the running surface used for vehicle guidance and the beam directly transmitting the load of the vehicles to the ballast bed and the railway substructure. The first part of the thesis describes the characteristics of rails and provides a theoretical background relating to rail stresses resulting from traffic load, temperature change and production procedures. When rail vehicles move, enormous contact stresses are produced in the contact zone between the wheel and the rail, which often causes damage to the running surface. Curves with smaller diameters cause particular wear of the rails because of the strongest dynamic effects of the vehicle on the rail. The thesis thus presents the most common surface defects, defines rail wear and outlines currently available techniques of rail grinding and lubrication. In the last few decades, only continuous welded tracks have been consistently installed. To this end, the second chapter describes the procedures and conditions for the construction and welding of rails into continuous welded tracks as provided for in the Rules on railway line superstructure published in the Official Gazette of the Republic of Slovenia, No. 92/2010. As for rail welding, special emphasis is given to aluminothermic welding which is one of the most established procedures for rail welding on the ground.
