Download availability

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.

Validation details

⚠️10 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-04-16 at 09:12 Europe/Paris using the MobilityData GTFS-RT validator.

Warnings

vehicle_id not populated W002 3 errors

vehicle_id should be populated for TripUpdates and VehiclePositions

Sample errors

trip_id 6 vacances 08:45 does not have a vehicle_id
trip_id 1 vacances 8:39 does not have a vehicle_id
trip_id 2 vacances 08:56 does not have a vehicle_id

Header timestamp is older than 65 seconds W008 1 error

The data in a GTFS-realtime feed should always be less than one minute old

Sample errors

header.timestamp is 6 min 25 sec old which is greater than the recommended age of 65 seconds

schedule_relationship not populated W009 6 errors

trip.schedule_relationship and stop_time_update.schedule_relationship should be populated

Sample errors

trip_id 6 vacances 08:45 stop_sequence 22 (and potentially more for this trip) does not have a schedule_relationship
trip_id 6 vacances 08:45 does not have a schedule_relationship
trip_id 1 vacances 8:39 stop_sequence 17 (and potentially more for this trip) does not have a schedule_relationship
trip_id 1 vacances 8:39 does not have a schedule_relationship
trip_id 2 vacances 08:56 stop_sequence 5 (and potentially more for this trip) does not have a schedule_relationship
