During operation of electric locomotives there is the possibility of wheel spinning on the discs bandages. The main cause leading to rotating bandages is their thermal request during braking failure of locomotive while operation. Kinetic energy in the locomotive braking is converted into heat that is transmitted to the bandage. Because of overloading of the bandaged wheels the phenomena of bandages weakening combined with tread defects appears. This danger exists especially when train brakes on long slopes and with high gradients. The aim of the paper is to determine by calculation the maximum temperature incurred during braking so as to tread depth and tire, both for new and for used bandages for the case of stopping when breaking.
