CONTINUOUSLY WELDED RAIL (CWR) TRACK BUCKLING AND SAFETY CONCEPTS
Last modified: 2017-02-28
The main disadvantage of continuously welded tracks is reflected in the limited freedom of expansion and contraction of the rails due to temperature changes. As a consequence, large longitudinal forces induced in the rails lead to rail deformation and lateral and longitudinal displacements of the track. This paper will present a methodology for ensuring stability in the CWR track (leaflet UI C 720), and will make its comparison with the calculation method of the CWR track defined in the applicable regulations, on the lines in operation in Bosnia and Herzegovina.
