Syntax

Autoexport from the XML-Schema for element IL:hasElementGroupType of railML® version 3.2
Documentation Classification of element groups used for operation from the interlock.
Subschema interlocking
Parents* usesTypes
Children any (0..*), designator (0..*)
Attributes:
  • elementGroupType: The classification of the element group. (obligatory; xs:string; patterns: other:\w{2,})
Possible values:
  • switchStaggering
  • catenary
  • elementBlocking
  • automaticRouteSetting
  • automaticTrainRouting
  • callOn
  • emergencyStop
  • switchHeating,

  • 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.

Semantics

Best Practice / Examples

Dependent on the operating rules of an infrastructure manager there are often groups of elements known to the interlocking that can be used to perform one operation to all members of the group at once. This grouping can have one of the following basic classifications:

  • automaticRouteSetting – Group of signals for activating and deactivating the ARS mode for all elements within the group.
  • automaticTrainRouting – Group of signals for activating and deactivating the ATR mode for all elements within the group.
  • callOn – Group of signals for which the activation of call-on aspect is allowed simultaneously. This is used if no particular routes are required for call-on aspect.
  • catenary – Group of elements which are related to one electrical section of catenary. Although the catenary switch status is normally not commanded from the interlocking, its status may be indicated and considered in interlocking. The related elements shall be reference to TVD sections as representation of track sections, switches etc.
  • emergencyStop – Group of signals which can be commanded to stop with one special command.
  • elementBlocking – Group of same type elements that can be blocked or unblocked from operation.
  • pointHeating – Group of switches for which the point heating devices are controlled together.
  • pointStaggering – Group of switches for which the point staggering is activated or deactivated together. The point staggering allows the automatic switching of switches if requested by any route.
  • other:… – The element group is of another type. This is the optional extension of the list. Each entry needs to start with the string “other:” and shall have at least two letters in addition.


The example shows the definition of a signal emergency stop group.

<hasElementGroupType id="estop01" elementGroupType="emergencyStop">
        <designator register="_SimpleRegister" entry="Emergency Stop 01"/> 
</hasElementGroupType>

The use of such an emergency stop group within <signalBox> is shown here. The group contains all main signals of station ARN.

<implementsElementGroup id="estopARN">
        <designator register="_SimpleRegister" entry="Stop ARN"/>
        <groupType ref="estop01" />
        <refersToMember ref="mb_sig01" />
        <refersToMember ref="mb_sig02" />
        <refersToMember ref="mb_sig03" />
</implementsElementGroup>
