A basic study of wheel/rail abrasion. 4. Lab. Simulator rigs (TN-TRIB-1)

As planned originally, the study of wheel/rail adhesion involves first identifying the contaminants found on running rails, and secondly studying their effect on friction using wheel/rail simulation machines in the laboratory. Report CR.46 described the techniques developed to sample and to study contaminants from the rail head. This present report...
