Hi-rail wheel assembly for improved traction

摘要: An improved hi-rail wheel assembly includes a frame connected to an axle tube surrounding axle, pair of railway wheels mounted in spaced relation on the tube, first pivotal links between and second axle. The is attached conventional roadway vehicle such that extension said effects downward lowering from lifts whereby tires engage railroad track, retraction upward lifting towards ground surface or roadway.
