Syntax

Autoexport from the XML-Schema for element IL:aspectRelation of railML® version 3.2
Documentation One aspect relation has a) one master signal showing a given aspect b) one or more slaves showing a given aspect. The slave aspect depends on the master aspect. c) an optional overlap when the master aspect is at danger. The path from slave to master may contain switches. The switch positions are given in order to unequivocally determine the path.

Attributes:
  • passingSpeed: The speed in km/h signalled by the slave aspect, i.e. the speed that the train must respect when passing the slave signal (at route entry). (optional; xs:decimal),

  • expectingSpeed: Maximum signalled speed in km/h at master signal (aka target speed). (optional; xs:decimal),

  • endSectionTime: The end-section of a route is the section between the closed route exit signal and the previous slave signal. Commonly, the interlocking revokes (part of) the route when this time period is passed. (optional; xs:duration),

  • id: unique identifier (optional; xs:string; patterns: (urn:uuid:)?[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}|\{[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\})
*Notice:
Elements may have different parent elements. As a consequence they may be used in different contexts.
Please, consider this as well as a user of this wiki as when developing this documentation further.
Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.
