Abstract
The adhesion between a locomotive drive wheel and supporting rail can be substantially increased by application of a powder mixture that contains a hard particle constituent preferably including alumina, a soft particle constituent preferably including titania, and an iron oxide constituent. The mixture may be in the form of a dry powder, a paste with water or alcohol vehicle, or a metal composite that includes the powder.
