ABSTRACT:
Single-sided linear induction motors (SLIMs) suspended in proximity to the rail of a locomotive are energized to increase the effective adhesion between the locomotive drive wheels and the rail in response to the detection of an operating condition in which the tractive effort of the locomotive traction motors is limited by less than optimal adhesion. The SLIMs are energized in relation to the reserve power capability of the power source and the limit of tractive effort improvement. One method further employs sand dispensing units activated if the suboptimal operating condition is not alleviated by activation of the SLIMs. Another method uses the sand dispensing units first, and only activates the SLIMs if the suboptimal operating condition is not alleviated by activation of the sand dispensing mechanism.
