In order to better guide the design,laying and maintenance of welded turnouts,the effects of stress-free temperature difference between two railway lines on the rail displacement and temperature force of a welded turnout were investigated.

Thus, in order to guarantee the service life and safety of rail track, it is necessary to heat the rigid CWR track during track-laying to control stress-free temperature of rail.
