Semantics / Bedeutung

The element ocpTT describes a single point along the train path. The sequence of the ocpTT elements inside a trainPart has to be according to the train path. Normally, an ocpTT belongs to a station with an arrivial and departure time. But an ocpTT could also be a blocking signal with or without passing time, or some control point on the train path. It is alllways referencing a certain ocp defined in the infrastructure part, providing some timetable related information for it.

Das Element ocpTT beschreibt den einzelnen Punkt im Zuglauf. Dabei muss die Reihenfolge der ocpTT innerhalb eines Teilzuges trainPart mit der Abfolge der Punkte im Zuglauf übereinstimmen. Der ocpTT entspricht einem Fahrzeitmesspunkt. Ein Fahrzeitmesspunkt kann, muss aber keine Betriebsstelle sein. Meist ist ein ocpTT gleichzusetzen mit einen Bahnhof und der dortigen Ankunfts- und Abfahrtszeit. Es kann aber genausogut ein Blocksignal mit oder ohne Durchfahrtszeit oder auch ein beliebiger Messpunkt auf der Strecke sein. Der jeweilige ocpTT verweist immer auf einen in der Infrastruktur definierten ocp und beschreibt dessen Verwendung im Fahrplan.

Attributes of ocpTT / Attribute von ocpTT

  • ocpRef: reference on a ocp (required)
  • trackRef: reference on a track (optional)
  • trackInfo: free description of the station track (xs:string, optional)
  • ocpType: this is a mixture of two informations describing the action of the train at this ocp xs:string (optional)

Possible values:

  • stop = train is stopping at this ocp
  • pass = train is not stopping at this ocp
  • begin = possible for the first ocp, if train part begins at this ocp and is not part of a longer train path; (deprecated with 2.1:) the start of a train path should be detected by parsing the trains
  • end = possible for the last ocp, if train part ends at this ocp and is not part of a longer train path; (deprecated with 2.1:) the end of a train path should be detected by parsing the trains
  • remarks: free remark for further description (xs:string, optional)
  • trainReverse: is true if train changes direction at this station (xs:boolean, optional). After this station the rollingstock which is referenced in formationTT changes order. This attribute could also been set at the first station, indicating that the formation starts in the reversed order.
  • alignment: describes the alignment of the arriving train in relation to the point on a track referenced by ocpRef xs:string (optional)
  • head
  • center
  • rear
  • offset: describes the offset of the stopping point in relation to the point on a track referenced by ocpRef (tLengthM, optional)
  • shuntingTime: driving time used used inside a station (xs:duration, optional)

Best practice & Examples / Empfohlene Anwendung & Beispiele

The train is stopping in Zurich (referenced ocp) on track 12 (no reference here). It is stopping with its head 10 meters before actually reaching the crossSection of this ocp, which is assumed to be located at the buffer stop in the main hall of this station. Then the train is changing direction and leaving.
