LOCOMOTIVE ADHESION TESTS IN THE U.S.A.

Use of strain gauges on a traction motor pinion to measure transient torque loadings is described. The locomotive used for the tests was a 3-ft. 6-in. gauge diesel-electric equipped with GE 761 traction motors. To produce maximum loads on the pinion the tests were made at low speed or while stationary. Eight loaded coal wagons were coupled to the locomotive and the brakes were applied. Current to the motors was increased until wheel slip occurred on clean and rusty rails. The train was then accelerated with power supplied to one bogie only up to 18 mile/h so that wheel slip took place at various speeds. Readings of the strains produced were also taken for coasting down a gradient, and when an impact took place between the locomotive and train. Several of the torque readings are given.
