Unloading of wheel/rail contact force - a preliminary investigation into the possible influence of track/vehicle dynamic interaction upon adhesion (IM-TS-007)

In November 1970 a very simple and limited study (reference 5) was reported on the conditions required to induce dynamic forces at the wheel/rail contact sufficiently high to overcome the static wheel load, and thus momentarily reduce adhesion to zero. An estimate was thus made of the amplitudes of loaded...
