ABSTRACT:
A device for the replacement of wheels on trains comprising a generally flat framework having a longitudinal opening extending therethrough, a first wheel receiving area rigidly affixed to the framework for abutting a surface of a wheel, and a second wheel receiving area rigidly affixed to the framework and disposed distal from the first wheel receiving area on the framework. The longitudinal opening receives the periphery of a train wheel. The framework includes a first longitudinal member, a second longitudinal member, and a transverse member rigidly connected across the longitudinal members for maintaining the longitudinal members in parallel alignment. The longitudinal opening has a width sufficient, in combination with the thickness of the longitudinal members, to cause the periphery of the train wheels to raise above the top surface of a railroad track. The wheel receiving areas comprise a plurality of abutment members positioned for the receipt of train wheels removed from a train and of replacement train wheels. Pull rings are rigidly affixed at the ends of the framework for attachment to an external pulling mechanism.
