Best practice & Examples / Empfohlene Anwendung & Beispiele

The following example (taken from SimpleExample) shows how a signal may reference a connected train protection element. The main signal "69A" is a combined signal that works as home signal for the station referenced by the ID "ocp01". This signal references a train protection element group:

<signal id="tr03_si07" pos="3800" absPos="4300" dir="up"
        name="69A" xml:lang="de"
        function="home" type="combined" ocpStationRef="ocp01">
  <trainProtectionElementGroupRef ref="tr03_tpeg01"/>
</signal>

The referenced train protection element group contains one Indusi magnet, which is positioned at the same track location like the signal:

<trainProtectionElements>
  <trainProtectionElement id="tr03_tpe01" pos="3800" absPos="4300" dir="up" 
                          medium="magnetic" trainProtectionSystem="Indusi"/>
  <trainProtectionElementGroup id="tr03_tpeg01">
    <trainProtectionElementRef ref="tr03_tpe01"/>
  </trainProtectionElementGroup>
</trainProtectionElements>
