We used the finite element method to establish a technique to precisely evaluate an axial force in rail and a rail expansion and contraction when turnouts exist in succession on a CWR on a ballasted track on earth roadbed or on a ballastless track of viaduct. We carried out a site test in a CWR track section where two turnouts exist in succession on a ballasted track, and the test results were compared with analytical results. We applied this technique to analyzing a rail axial force characteristic of a CWR connected with a turnout directly fastened to viaduct, and clarified the relationship between length of a girder bridge, arrangement of girders and an axial force in rail.
