Ready to send to the agency
Hi Cat Tran Shuttle team, Service data ended 1711 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist. The fix is usually one export setting: Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change. Your feed is produced by Trillium, so the quickest path is usually forwarding this to your Trillium contact. This came from your GTFS data quality scorecard, which checks the feed you publish and lists the fixes in plain language: https://gtfsscorecard.org/agency/cat-tran-shuttle/

agency_id and NTD ID: Not checked yet. Setting your GTFS agency_id to your five-digit NTD ID is an optional way to line a feed up with its National Transit Database record. FTA links the two on your P-50 form, so it is not a required feed change. We don't have your NTD ID on file, so this is not checked yet.
