Abstract

Creep curves characterise the behaviour of frictional forces at the wheel-rail interface. This study used the V-Track test rig to measure lateral and longitudinal creep curves under clean and dry contact conditions with practical wheel-rail contact pressures. The measured lateral and longitudinal creep curves were cross-compared to estimate the coefficient of friction of the V-Track. The measurement results and findings demonstrate the reliability of using the V-Track test rig to study the wheel-rail frictional rolling contact and to accurately measure the coefficient of friction at the wheel-rail interface, highlighting its significance in railway engineering and operational safety studies.
