The main results of the study obtained from testing gondolas on trucks with diagonal ties as they move on straight and curved track sections as well as turnouts. An assessment of the safety factor against the gathering wheel rail lateral forces transmitted from the wheel on the rail the relationship of forces to the frame static load from wheel pairs on rails and smooth progress indicator.
