Introduction
Catenary Signal is a railway signal that gives train driver:
- information about the status of the overhead electrification system (catenary), such as whether the power is switched on or off in a certain section of the track;
- the command lower or re-position the pantograph[1].
Switzerland. The lower signal shows that the pantograph has to be lowered because the catenary ends. In other situations it means stop for vehicles with a raised pantograph.

Attributes:
- type: specifies whether signal is of type announcement or execution (optional;
xs:string)
- Possible values:
- announcement: informs about incoming need of an action related to catenary, e.g. lower pantograph
- execution: marking a beginning of a section with changed catenary conditions, e.g. lower pantograph

*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.
