*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.

Semantics

Best Practice / Examples

A route relation states the conditions that must be fulfilled for the route start signal to be open. The relation consists of the affected route and any track asset with its related state. Subsequently the signal may only open when the relation is fulfilled. One possible use is for definition of specific flank protection conditions.

Note that these relations may well be captured in a control table, once it is implemented in the schema. Therefore, the use is optional.

The relationship is described in <routeRelation> for the various types of assets. For details refer chapter 1.1.15above.

  • <requiredSwitchPosition> – This is the reference to the related switch, its position and the level of enforcement.
  • <requiredDerailerPosition> – This is the reference to the related derailer, its position and the level of enforcement.
  • <requiredCrossingPosition> – This is the reference to the related movable crossing, its position and the level of enforcement.
  • <requiredDetectorState> – This is the reference to the related detector, its state and the level of enforcement.
  • <requiredSignalAspect> – This is the reference to the related signal, the aspect it shows and the level of enforcement.
  • <requiredSectionState> – This is the reference to the related TVD section, its state and the level of enforcement.
  • <requiredKeyLockState> – This is the reference to the related key lock, its state and the level of enforcement.


The extract shows the relationship between the occupation status of the start track A02T and the route from start signal 68N1 to destination signal 69A.

<routeRelation id="rtr01">

                        <refersToSection ref="A02T" />
                </relatedSectionAndVacancy>
        </requiredSectionState>
</routeRelation>
