Syntax

Autoexport from the XML-Schema for element IS:bufferStop of railML® version 3.2
Documentation represents a buffer stop as a node element. A buffer stop or bumper (US) is a device to prevent railway vehicles from going past the end of a physical section of track [wikipedia].

*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.

Semantics

Best Practice / Examples

The Simple Example contains five buffer stops as part of the <functionalInfrastructure>. Four of them are located at the ends of the railway line "6869" in kilometre 0.000 and kilometre 5.000. They are of type fixedBufferStop. The fifth <bufferStop> is located on a siding track that is not part of the railway line "6869" and therefore does not have a railway line coordinate. The following code snippet summarizes the buffer stop model.

<functionalInfrastructure>
      <bufferStops>
        <bufferStop id="bus01" type="fixedBufferStop">
          <spotLocation id="bus01_sloc01" netElementRef="ne_a01" applicationDirection="reverse" pos="0.0">
            <linearCoordinate positioningSystemRef="lps01" measure="0.0"/>
          </spotLocation>
        </bufferStop>
        <bufferStop id="bus02" type="fixedBufferStop">
          <spotLocation id="bus02_sloc01" netElementRef="ne_a02" applicationDirection="reverse" pos="0.0">
            <linearCoordinate positioningSystemRef="lps01" measure="0.0"/>
          </spotLocation>
        </bufferStop>
        <bufferStop id="bus03" type="fixedBufferStop">
          <spotLocation id="bus03_sloc01" netElementRef="ne_b01" applicationDirection="normal" pos="500.0">
            <linearCoordinate positioningSystemRef="lps01" measure="5000.0"/>
          </spotLocation>
        </bufferStop>
        <bufferStop id="bus04" type="fixedBufferStop">
          <spotLocation id="bus04_sloc01" netElementRef="ne_b02" applicationDirection="normal" pos="450.0">
            <linearCoordinate positioningSystemRef="lps01" measure="5000.0"/>
          </spotLocation>
        </bufferStop>
        <bufferStop id="bus05" type="sleeperCross">
          <spotLocation id="bus05_sloc01" netElementRef="ne_b05" applicationDirection="reverse" pos="0.0">
          </spotLocation>
        </bufferStop>
      </bufferStops>
      ...
    </functionalInfrastructure>
Summary
  • buffer stops are usually located on the microscopic topology level.
