Wheel–rail interface

The wheel–rail interface is the contact area where wheel–rail interaction between wheels and rails in railways takes place.[1] This interaction is a specialist subject covering the design and management of the very high stresses in the small contact area between a steel wheel and steel rail. The focus is on safety improvement, maintenance and replacement costs reduction, downtime reduction, and energy and environmental management.[2][3] The surface of the wheel that rests on the rail is known as the tread. Wheels can have either a single flange on the gauge side of the rail or two flanges, one on each side of the rail.[4]
