Railway applications - Track - Track alignment design parameters - Track gauges 1435 mm and wider - Part 2: Switches and crossings and comparable alignment design situations with abrupt changes of curvature
This European Standard specifies the rules and values for the track alignment design parameters used to determine the maximum operating speeds over tracks with abrupt changes in curvature and, consequently, abrupt changes of cant deficiency. Such conditions occur in the following situations: - in the diverging tracks in switch and crossing layouts; - when it is not practical to design an alignment with transition curves; - if the length of a transition curve is less than the minimum required for plain line track. Engineering requirements specific to the mechanical behaviour of switch and crossing components and subsystems are to be found in the relevant standards. This European Standard presupposes that the homologation of the operating vehicles will be valid and specified for conditions corresponding to the limiting values specified in this European Standard. This European Standard is applicable to abrupt changes in curvature in switch and crossing layouts and plain lines with track gauges of 1435 mm and wider. Annex C is applicable to track gauges wider than 1435 mm. This Eu
