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
❌3 errors, 2 warnings
Validation carried out using the current GTFS file and the GTFS-RT the 2026-03-31 at 09:13 Europe/Paris using the MobilityData GTFS-RT validator.
Errors
Sequential stop_time_update times are not increasing E022 3 errors
stop_time_update arrival/departure times between sequential stops should always increase - they should never be the same or decrease.
Sample errors
- trip_id 4888935818854400:7 stop_sequence 6 arrival_time 09:13:38 (1774941218) is equal to previous stop departure_time 09:13:38 (1774941218) - times must increase between two sequential stops
- trip_id 4888935818854400:7 stop_sequence 8 arrival_time 09:17:18 (1774941438) is less than previous stop departure_time 09:20:28 (1774941628) - times must increase between two sequential stops
- trip_id 4888935818854400:7 stop_sequence 8 departure_time 09:17:28 (1774941448) is less than previous stop departure_time 09:20:28 (1774941628) - times must increase between two sequential stops
Warnings
vehicle_id not populated W002 1 error
vehicle_id should be populated for TripUpdates and VehiclePositions
Sample errors
- trip_id 4832659147587584:4 does not have a vehicle_id
ID in one feed missing from the other W003 1 error
a trip_id that is provided in the VehiclePositions feed should be provided in the TripUpdates feed, and a vehicle_id that is provided in the TripUpdates feed should be provided in the VehiclePositions feed
Sample errors
- trip_id 4832659147587584:4 is in TripUpdates but not in VehiclePositions feed
