A track vacancy detection (TVD) section reports train occupancy to the interlocking. This is a logical unit characterised by the delimiters of the section. Typically, a section is delimited by two insulated track joints or axle counters at the extremities. Sections with a switch or a crossing can have several such limits.<br/>
Attribute
Public EntityILref
  hasDemarcatingBufferstop
Details:
position=1
Notes: Reference to physical track ends, e.g. buffer stop, as limit of the section.<br/>
Public EntityILref
  hasExitSignal
Details:
position=2
Notes: Reference to delimiting signals for leaving the TVD section.<br/>
Public EntityILref
  hasDemarcatingTraindetector
Details:
position=3
Notes: Reference to the physical train detection points, e.g. axle counter point, insulated rail joint, used as limit of the section.<br/>
Public EntityILref
  hasResetStrategy
Details:
position=4
Notes: Reference to the Infrastructure Manager specific reset strategy for this TVD section.<br/>
Public TrainNumberFieldRef
  hasTrainNumberField
Details:
position=5
Notes: Reference to the train number field(s) for this TVD section<br/>
Public EntityILref
  hasTrackElement
Details:
position=6
Notes: reference to any track asset (trackIL, switchIL, derailerIL, movableCrossing) in IL part<br/>
Public boolean
  isBerthingTrack
Details:
Notes: True, if this section is part of a berthing track, i.e. track where trains may halt and change direction. Typically, an Interlocking assures that trains progress from section to section in an ordered sequence (aka. two/three phase release). This check would fail when a train changes direction. If this attribute is true, the interlocking doesn't carry out this check for this section.<br/>
Public duration
  residualRouteCancellationDelay
Details:
Notes: The delay after which the interlocking may clear a partial route left by an unusual train run. The timer starts running when the interlocking accepts the signal man request to clear the section (DE: Restfahrstrasse auflösen) or when the interlocking algorithm detects that the train has set back (automatic route release).<br/>
Public duration
  partialRouteReleaseDelay
Details:
Notes: Delay time after which the section may be released for use in a new route<br/>
Public tTvdSectionTechnologyTypeExt
  technology
Details:
Notes: The technology used for the TVD section to detect the presence or absence of rail vehicles. <br/>
Public tFrequencyHertz
  frequency
Details:
Notes: The frequency in Hertz used for the TVD section in case of a track circuit. Shall be zero for direct current.<br/>
Tag Value
mixed false
Details:
Values: true | false
Default: false
Description: Determines whether this element may contain mixed element and character content.  Refer to the W3C XML Schema recommendation
modelGroup sequence
Details:
Values: all | sequence | choice
Default: sequence
Description: Overrides the package-level default model group
nillable false
Details:
Values: true | false
Default: false
Description: As defined by XML Schema specification
Property Value
isFinalSpecialization: 0
