The study deals with the investigation into the possibility of transporting containers in the open wagon the floor of which is formed by discharge doors and the determination of their strength. The following two load modes for the discharge door were taken into account: the vertical load on the discharge door through the fitting stop and the vertical and longitudinal loads. To determine the dynamic load as a component of the vertical load acting on the discharge door, mathematical modelling of the vertical dynamics of an open wagon loaded with containers was carried out. The bouncing oscillations were also taken into account. The acceleration value was determined; it was further used for strength calculation of the discharge door using the finite element method. It was found that in the first load diagram for the discharge door, the maximum stresses occurred in the eye hinge and they amounted to 404 MPa; in the second load diagram the maximum stresses were 570 MPa. The resulting stress values significantly exceeded the permissible ones. This has proven that the transportation of containers in the open wagon the floor of which is formed by discharge doors is not permissible. The study conducted may contribute to the development of recommendations on using open wagons for transportation of containers.
