The adhesion level between wheel and rail has been since the beginning of railway a crucial parameter in the design and operation of rail vehicles. In the last decades, many railway organizations have suffered from low adhesion problems as consequence of the increased exploitation of the rail infrastructure. Leaves and water have been widely reported as major causes of low adhesion. Among the practical measures adopted, friction modification is one of the most popular used to enhance adhesion levels to the required minimum during traction and braking. In this paper, some results of investigations carried out with two friction modifiers are presented. Further, some of the desired properties of the friction modifiers to optimally overcome the slippery rails problem are discussed.
