Attributes: releaseSpeed: Release speed in km/h from controlled braking curve. (optional; xs:decimal), malfunctionSpeed: This constant indicates the maximum speed in km/h with which a train may travel past a failed signal. The malfunctioning signal cannot be opened. (optional; xs:decimal), approachSpeed: The maximum speed in km/h with which a train can approach the signal. This matches the Ka of the previous (=upstream) signal or speed sign. This is suitable for defining the line speed profile. (optional; xs:decimal), passingSpeed: Maximum speed in km/h beyond the signal. This is suitable for defining the line speed profile. (optional; xs:decimal), releaseDelay: Time to elapse between receiving the revocation command and before route release. (optional; xs:duration), function: Function of the signal for usage by the interlocking. This is in addition to signalType in infrastructure. (optional; xs:string; patterns: other:\w{2,}) Possible values: main repeater distant shunting barrage block junction exit intermediateStop intermediate entry, isVirtual: Often, users label signals virtual. A virtual signal can be a dummy-signal that is a software object in the interlocking but has no physical trackside presence. Such virtual signals can be useful for modelling speed steps; there need not be a physical signal but the interlocking enforces a different speed at the position of the virtual signal. The other way round, stand-alone boards that are not wired to the interlocking can be labelled virtual. Such stand-alone signals are of interest to simulations because when they affect driver behaviour thus influence train runs. (obligatory; xs:boolean), callOnAspectTime: time for duration to show call-on aspect on this signal (optional; xs:duration), sightDistance: The distance in metres the signal is visible in advance by the train driver. This might influence reaction times on changing aspects for simulation. (optional; xs:decimal), id: unique identifier (optional; xs:ID; patterns: (urn:uuid:)?[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}|\{[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\}); compare: Dev:Identities
*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.
