A REVIEW OF THERMAL DAMAGE IN RAILROAD WHEELS
The purpose of this paper is to provide a common starting point for further discussions on the subject of thermal damage in railroad wheels. The intent is to construct a simple explanation of a complex subject. Wheel design would be fairly straightforward if the wheel functioned only as a load bearing member, or only as an outlet for heat from braking. Because it serves both purposes, design problems compound. Balanced braking among all cars in the train is critical. A locomotive dynamic brake offers a huge outlet for braking heat. The paper discusses the contributions of better wheels, properly aligned brake rigging, and better brake shoes.
