ABSTRACT: Previous testing of lubrication systems at the Facility for Accelerated Service Testing (FAST) have stimulated a general interest in grease performance. The hi-rail grease test was conducted to evaluate four types of lubricant when used with a hi-rail track lubricator. In this test, the grease evaluation criteria were: the effect of initial lubrication on dry rail conditions; the change in. lubrication effectiveness during drydown; and the position-in-curve lubrication level. The testing suggests the conclusion that development of a grease specifically for use in a hi-rail lubrication system could provide 30-35 laps of service without wheel-slip problems.
