Description	This article follows up with the ideas of EUREKA Eurobogie and Footprint projects, the goal of which is to improve the suspension quality of rail and road vehicles and to find techniques for the measurement of the impact of the vehicle to the environment. Based on the tests realized on a shaker rig in the laboratory, the methodology for the track drop test was proposed. This method is suitable for the determination of the natural frequency and critical damping ratio of suspension system of railway wagons. Basic relations for the calculation of these values on the basis of time force and acceleration histories are given in the article. An example of the drop test with HAA coal wagon provided with composite suspensions is shown. Estimation of the dynamic loading coefficient based on the track drop test using MBS modeling is also introduced and a simple relation between drop and track force time histories is derived.
