Call-prep brief · checked 2026-06-30

Catalina Express

Grade F · 26.2 / 100

First check for this agency, so there is no trend yet.

For this call: lead with the grade and the three fixes below, then confirm the feed is current and the NTD details line up. Each fix is framed as a next step, not a failure.

What changed since the last check

No category changes since the last check.

Top three things to fix

  1. Add feed_start_date and feed_end_date to feed_info.txt and include calendar end dates in your export.

    Neither feed_info.txt nor the calendars state when service ends. Nobody can tell when this feed will go stale.

    Effort: Likely a one-time export setting.

  2. Review the rule documentation for 'missing_required_file' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    Missing required file (flagged by the MobilityData validator). See the linked rule for what this affects.

    Effort: Varies.

  3. Review the rule documentation for 'invalid_input_files_in_subfolder' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    Invalid input files in subfolder (flagged by the MobilityData validator). See the linked rule for what this affects.

    Effort: Varies.

NTD certification readiness: Not ready

Resolve this before you certify on the D-10. 3 validator errors to resolve. No service end date could be read, so currency is unknown.

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.
