Szukana fraza: [Abstrakt = "The data collected on the impact of additional stresses found on the rails had a direct correlation between the track and the bridge. The results displayed a need for the rail expansion devices to be placed in the track. Due to the fact that the stiffness of the supports had a significant effect on the stresses that developed, in order to increase the stiffness, an additional support structure was connected with footholds by means of faders which act as horizontal spring supports. The calculations have shown that the removal of the rail expansion devices has caused the additional stresses in the rails to fit within the allowable limits of the track. As a result of the removal they were more effective\; however, this was also due to length of expansion."]
