When a train arrives at chain signal A, both lines B and C are occupied. When one of the trains at B or C leaves, the chain signal A turns blue. If the path that is freed up does not coincide with the calculated path of the train waiting at A, as illustrated in the screenshot, the train at A will continue waiting for 30 seconds until a new path recalculation is triggered.

Expected behaviour: not sure if this is by design or not, but I would expect a path recalculation to be triggered as soon as the chain signal changes state. If this is not a bug, please consider this as a feature request.

Tested with version 0.16.22 (build 35382, mac, steam).
I am also attaching the log as requested by the bug reporting instructions, although it is largely irrelevant in this situation.

Thanks for the report. The game has no "wait on chain signal path to open up/change" logic so this would be a feature request.
