Attributes:
  • infrastructureManagerRef: reference to the infrastructure manager who owns the track (see <organizationalUnits> in <common>) (optional; xs:IDREF),

Possible values:
  • both
  • reverse
  • normal,

  • type: type of the track defining the general functionality of the track. (optional; xs:string)
Possible values:
  • mainTrack: A main track is either an open track between operational points or the extension of an open track within an operational point. It typically connects stations and is used for planned train journeys (trains in commercial operation or trains being moved between operational points). CH: Hauptgleis (signalisiertes Gleis). CZ: Hlavní kolej. DE: durchgehendes Hauptgleis. NL: Hoofdspoorweg. NO: hovedspor.
  • secondaryTrack: A secondary track is a track used for planned train journeys running in commercial operation or trains being moved between operational points, but it is not an open track between operational points or the extension of an open track. CZ: Spojovací kolej. DE: nicht-durchgehendes Hauptgleis. NL: Lokaalspoorweg. NO: øvrige
  • sidingTrack: Siding tracks are tracks that are not used for planned train journeys, except at the start and end of a train journey if the train is shunted to or from a parking spot. CH: Nebengleis (nicht-signalisiertes Gleis). CZ: Manipulacní koleje. DE: Nebengleis. NL: Raccordement. NO: Sidespor
  • connectingTrack: Connecting tracks are typically very short and connect other tracks. Examples are short track sections connecting two tracks where switches allow to move from one track to the other. CZ: Kolejová spojka. DE: Gleisverbindung. NO: øvrige,

  • id: the identifier of the object; this can be either of type xs:ID or UUID (obligatory; xs:ID); compare: Dev:Identities
*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

Open track is a track usually outside operational points. An open track shall have type “main”, this type shall carry on to the part of the track extending inside the station. Usually, the mileage is references from the “main” track. The number of main tracks in the operational point shall be the same as the number of open tracks entering the station.

Additional Information

Notes

Since the railway network topology in railML® 3.x is based on RailTopoModel® elements <netElement> and <netRelation>, the <track> has no topologic dimension. Considering the <track> as a pure NetEntity derived object that is placed on top of a topology, the track does not have to be defined that strictly. It is possible to allow for a weaker definition, too.
