Objective: to assess the force effect of heavy and long-component freight trains on the railway track by various measurement methods: Schlumpf, influence matrices and the two-section method (PGUPS). Methods: measurements of the assessment of the force effect of heavy and long-component freight trains on the railway track were carried out using the Schlumpf methods, influence matrices and the two-section method (PGUPS). Results: it was found that measurements of vertical dynamic forces by three methods are well correlated with each other, and the Schlumpf method gives overestimated results when measuring horizontal transverse force. Practical importance: the two-section method can be recommended for measuring the force effect of both new and upgraded rolling stock on the railway track, as well as for operated rolling stock in order to identify defects and deviations on the rolling surface of the wheels.
wheel-rail contact, interaction of rolling stock with the upper structure of the track, longcomponent trains, increased axial loads, curved sections of small radius, heavy traffic
