IL:overlapRelease

Documentation

Syntax

Autoexport from the XML-Schema for element IL:overlapRelease of railML® version 3.2 UML-visualization of IL
Documentation	Overlap is set in lockstep with the route. The interlocking releases the overlap when it is safe to presume that an approaching train will not overrun a closed destination signal. When the train occupied the last section (or destination area), an overlap release timer starts running. The timer value is defined by operational rules and the approaching speed. Upon expiry, the interlocking releases the overlap. Overlap is released together with the route or after expiration of the release timer. Overlap is released after a defined time in a timer that starts from a timerTriggerPoint.

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.
