speed
 


Scheme description / Schemenbeschreibung

Position of speed in the XML-Tree / Position von speed im XML-Baum

Multiplicity / Anzahl

[1..1]

Semantics / Bedeutung

The element <speed> defines a "very special kind of" speed profile for all tracks where the current <infraAttributes> are used per reference.

Attributes of speed / Attribute von speed

  • trainCategory This is a category name for trains. Don't confuse with <category>!
  • status
  • vMax
  • trainRelation (introduced with version 2.2) Reference to the part of the train from where the speed change is valid. Normally, a speed change with a speed that is higher than the permitted speed in the section before will be valid only after the end of the train has passed the speed change. On the contrary, a speed change with a speed value that is lower than the permitted speed in the section before applies already when the head of train passes the speedChange. This is the default value; define this attribute only if your train relation differs from this rule. See notes for further information.
  • signalised (introduced with version 2.2) Indicates whether the speed aspect is shown next to the track by a signal or panel (=true/1) or not (=false/0). For speed changes which are printed in a "Driver's timetable" only but not shown at track-site, use false/0. This is aimed to be used to create special caution for speed changes which are not shown at track-side by special 'highlighting' e. g. in the Driver's timetable. In the meaning of 'on the safe side' this may also apply to speed changes with no proper pre-signalisation (since the pre-signalisation is normally more important than the signalisation at the actual beginning of a speed restriction). A speed change is treated as not pre-signalised if there is at least one route at which a train can pass the speed change decreasing and did not pass any pre-signalisation for the speed reduction a proper braking distance before.

Syntactic Constraints / Syntaktische Beschränkungen

  • vMax tSpeedKmPerHour: xs:decimal, 5 digits and 1 fraction digit with minimum value 0, speed value measured in km/h, mandatory
(introduced with version 2.3): union of tSpeedKmPerHour and the enumeration value of "end"
  • trainRelation, optional, enumeration: "headOfTrain" / "midOfTrain" / "endOfTrain"; default: see explanation above
