- Partial Route
The elements of a route are automatically released after use by a train. This release can be for the whole route at once or parts of it. The trigger for release is the clearing of TVD sections after sequential occupation. Thus the TVD section are of interest for release groups as all other elements are indirectly included in such groups. If one or more TVD section is released in a group, the characteristics are detailed as partialRoute. However, if the interlocking in general releases each individual TVD section after use the release groups can be omitted.
The instantiation extends the abstract type of partialRoute by some additional elements and attributes.
The abstract class contains
- @delay – Duration after which the interlocking releases the partial route. Starts counting from the moment that all the conditions for release are fulfilled. This delay is engineered in static data. If not defined, the interlocking releases the group without delay. If the route has only one route release group then the set of TVD sections in the route is released en bloc with the delay given here.
- @typicalDelay – Duration after which the partial route is typically released. Use this delay for simulation purposes. Starts counting from the moment that the interlocking has received all conditions for the release. E.g. TVD sections in the group have been vacated, timers expired.
- <hasTvdSection> – The reference to the TVD section contained in the release group. There can be more than one section referred to.
