bucket, task group, or safety flag. Status Now can be ordered by each train’s first activity or
first safety activity.
Status Over Time

Due statuses
For each vehicle-or-component and task, usage since the last completed record is compared against the task’s interval and tolerances:Calculations
This differs by interval type :Secondary intervals and task types
Where a task has a secondary interval, the more severe of the two statuses wins — the “whichever comes first” rule. If the secondary cannot be evaluated, the primary stands.- One-time tasks are a simple “has it ever been done”: NOT DUE if a record exists, DUE otherwise.
- Seasonal tasks read NOT DUE outside their window, and behave exactly like recurring tasks inside it. The window handles year wrapping, so October-to-March works.
