Attributes of trainDetector / Attribute von trainDetector

  • id: XML-file-wide unique, machine-interpretable identity, required for later referencing that element internally. For a detailed explanation see Dev:identities.
    XML-Datei-weit eindeutige, maschineninterpretierbare Identität, die für die spätere interne Referenzierung dieses Elements erforderlich ist. Für eine detaillierte Erklärung siehe Dev:identities.
  • code (introduced with version 2.1): This is a short string for typical, specific abbreviations, used in different systems with the same understanding.
  • name: This is a short name for the current item.
  • description: This is a more detailed description as addition to the short name. It shall allow a short overview or hints to the contents of this data set.
💡 Please take into account our references to human-intepretable data fields.

Bitte berücksichtigen Sie unsere Hinweise zu menschen-intepretierbaren Datenfeldern.


  • xml:lang (introduced with version 2.1): This is a unique identifier of language. It uses basically the language standard IETF BCP 47 (external link) which may be different to ISO 639-1 (external link) or ISO 639-2 (external link). For mapping hints see relation to other standards (external link).
    This is used for defining name and description.
  • pos: This is the position on a track defined as distance from its start (trackBegin) regardless the "absolute mileage" in @absPos.
    Das ist die Position des Elements auf einem Track i.S. der realen Entfernung zum trackBegin. Sie ist damit unabhängig von der mit absPos modellierten Strecken-Kilometrierung.
🗒️ For an explanation of the differences between @pos and @absPos see <mileageChange>
  • absPos: This is the position on a track as absolute mileage/chainage.
    Das ist die Position des Elements im Referenzsystem der Strecken-Kilometrierung.
🗒️ For an explanation of the differences between @pos and @absPos see <mileageChange>
  • absPosOffset (deprecated with version 2.1): The semantics of this attribute aren't very clear. It seems to be redundant to the definitions with mileageChanges in "overlapping regions".
  • dir: This defines the validity of trainDetector along the track. Possible values are:
  • up: This denotes the direction from the <trackBegin> to the <trackEnd> (increasing relative position values).
  • down: This goes opposite to up (decreasing relative position values).
  • unknown: trainDetector is restricted to a certain direction, but this direction is not known.
  • ocpStationRef: This refers to the id attribute of the associated <ocp> element.
    (introduced with version 2.1)
  • controllerRef: This refers to the id attribute of the associated <controller> element.
    (introduced with version 2.1)
  • detectionObject Possible values are:

Notes / Anmerkungen

General information on positioning

Positive pos values describe the distance from the track's begin. The track length is derived from the pos value in <trackEnd>.

The absolute mileage refered to by absPos is usually found on technical drawings of the track layout or on mileage posts next to the track.
