*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 railway signalling has elements in addition to the signalbox and the controller, which are not directly related to a particular track. These more common elements are called “system asset”. As this can be a wide range of objects like RBC, Command and Control System, communication system, power supply, passenger information system suitable containers are to be defined in <assetsForIL>. These classes shall at least provide @id and <designator> as for all IL elements.
Currently there is only the container <powerSuppliesIL> in <assetsForIL>.
The power supply provides electrical power to the control and the field elements. It might be located at the signalbox or close to the particular field elements like signals or switches it is connected to. The detailed features like overall power or voltage levels are very specific for the manufacturer and the location it is installed. They are not included in railML.
The information of interest for the interlocking are these attributes:
- @numberOfSimultaneousSwitchingActuators – This is the maximum number of switch actuators that can be activated simultaneously with this power supply. In case of more switch actuators connected to this power supply are commanded for switching the interlocking will stagger their operation in order to avoid overload of the power supply.
- @signalVoltageMode – This gives the mode of switching signal voltage for day and night voltage. The values can be:
- automatic – The switching of signal voltage is done automatically according input from daylight detector.
- manual – The switching of signal voltage is done by manual operator command.
- nightOnly – The signal voltage is always kept on night voltage level as necessary for tunnel signals.
- none – The system does not know about any daylight dependent voltage adjustments.
The example below shows the instance of a power supply capable to activate four switch actuators at once and automatically changing the signal voltage between day and night value.
<powerSupplyIL id="ups01" numberOfSimultaneousSwitchingActuators="2" signalVoltageMode="automatic">
<designator register="_SimpleRegister" entry="UPS-ARN01"/>
</powerSupplyIL>
