The neutron stress measurement method was applied to evaluate residual stresses in a raliway rail whih was used in servive for some years, and a new wheel. The residual stress analyzer (RESA) at the Japan Atomic Energy Agency (JAEA) was used for the measurement. It was found that the residual stresses were almost cnmpressive except a small part of the rail. The normal stresses obtained showed almost similar values eah other, but theyvaried depnding on the position in transverse direction of the rail. The steep gradient of stress in depth dirction was also observed. The FEM analysis was conducted to compare with the neutron stress measurement. An area detector type stress analysis was also applied to the rail.
