In order to investigate the rail rollover phenomenon, a series of in-track tests were performed in Chicago, Illinois. During these tests, a single rail in the track structure was subjected to combinations of lateral, vertical, and longitudinal loading. The deflection of the rail was carefully monitored. The tests indicated that even under the most severe load combinations, the rail never did overturn although significant widening of the gauge was recorded. Additionally, the effect of the longitudinal loads in combination with the vertical and lateral loads was quite dramatic indicating the significance of this load component.
