Expansion of Application Range of Continuous Welded Rail Integrated with Turnout

We used the finite element method to establish a technique to precisely evaluate the axial force, expansion and contraction of rails in areas with turnouts in succession integrated with a CWR on ballasted track laid on an earth roadbed or on ballastless track of viaduct. We carried out an on-site test in a CWR track section where two turnouts are located in succession integrated with a CWR on a ballasted track, and the test results were compared with the analytical results. We applied this technique to analysis of the rail axial force characteristics of a CWR connected with a turnout directly fastened to viaducts, and clarified the relationship between girder bridge length, girder arrangement and axial force in rails.
