Multiplicity / Anzahl


Semantics / Bedeutung

The element formationTT describes how a formation is used for a trainPart.

Das Element formationTT beschreibt wie eine formation im Rahmen eines trainPart verwendet wird.

Attributes of formationTT / Attribute von formationTT

  • formationRef: This refers to the id attribute of the associated formation element.
  • weight: the real weight of the formation while in use, including any possible engine(s)
  • load: (introduced with version 2.1) the real load of the formation while in use, excluding any possible engine(s)
  • length: the real length of the formation while in use
  • speed: the real maximum speed of the formation while in use
  • timetableLoad: (introduced with version 2.1) planned load according to the timetable, excluding any possible engine(s)
  • orientationReversed: (introduced with version 2.2) this indicates, that the formation is not as referenced but in the reversed order
  • xs:anyAttribute: This provides an extension point for non-railML® attributes in a foreign namespace. How to use it?

Syntactic Constraints / Syntaktische Beschränkungen

  • length: xs:decimal, 6 fraction digits, length value measured in meter, optional

Notes / Anmerkungen

Due to the habits of railway terminology, "load" here means the mass of any wagons and carriages including their payload (passengers, freight) but does not include the mass of any engines. In the case the formation consists engines only (including multiple units), load is defined to be zero and does not include the mass of any passengers or freight (which may be conveyed or transported inside the engines or multiple units).

However, the attribute weight contains the total physical mass, always including all engines, multiple units and payload.

On the difference between ocpTT/@trainReverse and formationTT/@orientationReversed, see Reversing trains and formations.
