VARIABLES IN TRAIN RESISTANCE

A study has been made of train resistance and the variables that are important in the determination of the horsepower requirements for the movement of railroad cars total train resistance has been represented by several investigators as a second-order polynomial with the train velocity as the independent variable. The factors that influence train resistance are summarized as the journal-bearing friction, track resistance to rolling, wind resistance, curve and grade resistances, acceleration resistance, and starting resistance. Each of these factors is examined for its magnitude of contribution to total train resistance. The concepts of journal-bearing friction resistance and of track resistance as contributing elements are examined in their relationship to total resistance. Explanations of the various resistances are given in the light of bearing performance considerations and of the developments that have occurred in roadbed, track, and motive power during the years.
