We test this resource download availability every hour by making an HTTP HEAD request with a timeout of 5 seconds. If we detect a downtime, we perform subsequent tests every 10 minutes, until the resource is back online.

For SIRI and SIRI Lite feeds, we perform a GET request: a 401 or 405 status code is considered successful. In case of HTTP 500, the feed will be considered unavailable, unless the body appears to contain SOAP.

❌253 errors, 77 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-01-18 at 08:10 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

GTFS-rt trip_id does not exist in GTFS data and does not have schedule_relationship of ADDED E003 1 error

All trip_ids provided in the GTFS-rt feed must exist in the GTFS data, unless the schedule_relationship is ADDED

Sample errors

trip_id 9526 does not exist in the GTFS data and does not have schedule_relationship of ADDED

GTFS-rt route_id does not exist in GTFS data E004 1 error

All route_ids provided in the GTFS-rt feed must exist in the GTFS data

Sample errors

route_id 0095 does not exist in the GTFS data routes.txt

GTFS-rt stop_id does not exist in GTFS data E011 1 error

All stop_ids referenced in GTFS-rt feeds must exist in GTFS stops.txt

Sample errors

trip_id 9526 stop_id SEBRG2 does not exist in GTFS data stops.txt

Header timestamp should be greater than or equal to all other timestamps E012 65 errors

No timestamps for individual entities (TripUpdate, VehiclePosition) in the feeds should be greater than the header timestamp

timestamp is in the future E050 63 errors

All timestamps must be less than the current time

Sample errors

trip_id 5456407 timestamp 08:14:10 (1768720450) is 4 min 8 sec greater than 08:10:01 (1768720201709) - the current time in milliseconds
