Changes

* It was found that a route could be set across a level crossing that had only just begun to close to trains if the route setting was done very quickly. The final signal before the crossing stayed at red so trains would be protected but the route was present and shouldn’t have been. The program check routine has now been modified to include routes that are in course of being set in addition to routes already set.
