Introduction

Documentation

Syntax

Autoexport from the XML-Schema for element IS:signalConstruction of railML® version 3.2
Documentation child element for construction details of the (physical) signal
Subschema infrastructure
Parents* signalIS
Children None
Attributes:
  • height: height of the main light point (or upper edge for semaphore/panel signals) above the upper edge of the associated (or possibly next track) in [m] (optional; xs:decimal),

  • positionAtTrack: position of the (physical) signal/panel in relation to the railway track where it belongs to and the signal/panel application direction (optional; xs:string)
Possible values:
  • above: signal is above the track
  • left: signal is to the left of the track according to its application direction
  • right: signal is to the right of the track according to its application direction,

  • type: distinguish between light, form and virtual signals (optional; xs:string)
Possible values:
  • board: a board is a panel that expresses one (unchangeable) signal aspect
  • light: a signal with lamps
  • pole: the signal aspect is expressed via a color code painted on the pole
  • semaphore: a signal, where the signal aspect is expressed by the position of its movable arms
  • virtual: signal has no physical presence on the track. Command is passed in some other way, e.g. radio
*Notice:
Elements may have different parent elements. As a consequence they may be used in different contexts.
Please, consider this as well as a user of this wiki as when developing this documentation further.
Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.
