Influence of leaf, humidity and applied lubrication on friction in the wheel-rail contact: Pin-on-disc experiments

A novel test method has been used to study how applied and natural lubrication (leaf and humidity) influences the coefficient of friction in the wheel–rail contact. A pin-on-disc tribometer placed in a climate chamber was used as the test equipment. The pin-on-disc contact simulates the wheel–rail contact caused by commuter...
