Abstract
A railcar indexer system is disclosed that includes a design that enables extremely high loads to be moved without exceeding present railcar limitations. The railcar handling system of the present invention employs hydraulically-operated indexers that divide the load between consecutive dog carriages that, in turn, operate to apply force to railcar bogey frames or axles on consecutive railcars. This transfers a large amount of force to be applied to a lead railcar and enables a much larger amount of force to be applied to the next railcar and a larger total force to be applied to a string of railcars.
