Rail-Wheel Friction Management in Rail System Vehicles

In rail systems, which is one of the reliable transportation ways of our age, the first interaction between vehicle and infrastructure starts with rail and wheel contact. In cases where the friction that will arise from the rail-wheel contact is high, abrasions and noise will occur on the wheel and the rail outside the allowable limits. In cases where the friction is not sufficient, the wheel will slide on the rail or the vehicle will skid during the first run. For these reasons, it is necessary to increase or decrease the friction according to the line and environmental conditions. Systems called lubrication system to reduce friction and sanding system to increase friction are used in vehicles. In this study, the basic components of the lubrication system and sanding systems were examined and lubrication and sanding systems designed for a tram were introduced.
