*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.

Additional Information

Notes

Users can refer to the train protection system using the attribute @trainProtectionSystem that shall link to the codelist TrainProtectionSystems.xml, section trainProtectionSystemsAtTrack. Only if this list does not contain the specific train protection system to be modelled, it shall be described in its functionality using attributes @medium and @monitoring.
