The paper proposes a method of running strength tests of cast parts of a three-axle bogie model UVZ-9M. The developed technique allows using strain gauges to determine the loading of cast parts of the UVZ-9M triaxial bogie for further assessment of their residual life and the possibility of extending their service life. In addition, the proposed methodology describes the procedure for measuring the coefficients of vertical and horizontal dynamics of sprung and unsprung parts of the trolley. This technique is suitable for conducting running strength tests in both loaded and empty conditions.
