Abstract:Running resistance of ore trains consisting of Uad type wagons is determined from full scale measurements on Malmbanan. Tests are also run in curves with the Uad and an ore wagon equipped with a bogie allowing the axles to align themselves radially. Influence of speed, axle load, curve radii and train length are studied and quantified. The running resistance is parameterised and expressed in a general way so it can be calculated for any Swedish ore train consisting of Uad-type wagons. The study shows that the increase in running resistance is linear due to increasing axle load on tangent track and train length.
