In this study, in order to clarify the causes of rail fracture at leakage area in tunnels, past cases of rail fracture were analyzed and the causes were estimated. In addition, in order to clarify the effects of head unevenness and floating sleepers, which are considered to be direct causes of rail damage, on the stress generated by rail bending stress, we extracted the locations where these stresses were significantly generated from track survey data and conducted measurement tests of rail bending stress during train running. Based on these results, the mechanism of rail fracture at the leaking area was discussed.
