CWR track, ballast longitudinal resistance, rail axial displacement, local rail temperature changes

In the paper several specified models of ballast longitudinal resistance to behaviour of CWR track have been analysed. The considered problem is connected with local track segments in which horizontal displacements of rail cross-sections occur. Th...
