Angle of attack is one of the most important parameters influencing wheel and rail wear. Some experiments conducted on the IIT-GMEMD 1/4.5 test facility to study wear of wheels and rails are reported. The angle of attack range covered is from theta = 0.25 degrees to theta = 1.00 degrees. The drastic reduction in wheel and rail life at high angles of attack is highlighted by comparison of the test results at 0.25 degrees and 0.76 degrees angle of attack. The adhesion-creepage behavior of wheel-rail contact in the longitudinal and lateral directions is examined and shown to be qualitatively similar for the two directions. Validity of the flange wear indices, obtained by the friction center method and those proposed by CN and Ghonem and Kalousek, are checked against the wear rates obtained in laboratory experiments.
