“…Scaled roller rigs typically use wheel in scale 1:4 [87,101] or 1:5 [102]. Similar wheel sizes are used in the test rigs in [18,[103][104][105][106], with wheel diameters between 170 and 300 mm. The rail disc of scaled roller rig is either of the same size as the wheel [106] or up to about five times larger [101,105].…”

“…The prevalent number of measurements consider the creep forces in longitudinal (running) direction, employing traction or braking torques transmitted between aligned rollers, e.g. [98,100,103,104,106,107]. On real vehicles, the creep forces on straight track are determined based on the traction motor armature current [29] or other sensors, e.g.…”

This paper surveys advances in the understanding and modelling of wheel-rail creep forces. The main focus is placed on tribological aspects, for which significant progress was made in the past two decades. We emphasise the role played by the surface conditions, i.e. the presence of liquid and solid layers, surface roughness, and nearsurface plastic deformation. As these surface conditions may change over time, transient changes may be obtained in the creep force characteristic. This brings feedback into the picture, with consequences and opportunities for optimised adhesion recovery, traction control, and braking systems.
