Abstract
The article deals with the heating process of the axle-boxes ofrolling stock when the train is in motion and discusses the forcesacting on the wheel-set when rolling stock moves along the trackcurves. The paper analyses scientific publications relevant tothe forces acting on the wheel-set of rolling stock and focuseson the axle-box heating process. The article also discusses theresults of theoretical studies on wheel-set forces that affect theheat exchange process of axle-boxes for a railway vehicle. Theresearch has determined a change in heating temperatures ofdifferent axle-boxes of rolling stock and reasons for their variationsand tendencies. The paper has estimated an effect of thetrain running along the track curves on the heating intensity ofthe axle-box. Finally, valid conclusions and recommendationshave been provided.
