Running Resistance - Results and Analysis of Full-Scale Tests with Passenger and Freight Trains in Sweden

Experimental results of running resistance tests are presented in this paper. The research determines running resistance for conventional passenger and freight trains, as well as for the X2 high-speed train. Such influential variables as speed, the number of axles, the number of coaches, axle load, track type, and train length are extensively studied. Running resistance is expressed in a general form by a second degree polynomial comprised of three terms that are functions of these variables. Regarding the first term, it is speed independent and varies per the number of axles, axle load, and type of track. Variations of speed and train length influence the second term. Axle load shows no distinguishing influence. The third term, which is related to the air drag, varies according to speed squared and train configuration. It is comprised of two parts. Part one is constant, with a dependence upon the front and rear of the train. Part two shows increases that are approximately linear with train length.
