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

❌7 errors, 1,274 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-01-20 at 08:06 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Sequential stop_time_update times are not increasing E022 6 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 1288 stop_sequence 15 arrival_time 07:54:17 (1768892057) is equal to previous stop departure_time 07:54:17 (1768892057) - times must increase between two sequential stops
trip_id 1285 stop_sequence 8 arrival_time 07:55:38 (1768892138) is equal to previous stop departure_time 07:55:38 (1768892138) - times must increase between two sequential stops
trip_id 1279 stop_sequence 13 arrival_time 07:53:01 (1768891981) is less than previous stop arrival_time 08:22:22 (1768893742) - times must increase between two sequential stops
trip_id 1279 stop_sequence 13 arrival_time 07:53:01 (1768891981) is less than previous stop departure_time 08:30:22 (1768894222) - times must increase between two sequential stops
trip_id 1279 stop_sequence 13 departure_time 07:53:12 (1768891992) is less than previous stop departure_time 08:30:22 (1768894222) - times must increase between two sequential stops

stop_time_update departure time is before arrival time E025 1 error

Within the same stop_time_update, arrival and departures times can be the same, or the departure time can be later than the arrival time - the departure time should never come before the arrival time.

Sample errors

trip_id 758 stop_sequence 4 departure_time 08:05:18 (1768892718) is less than the same stop arrival_time 08:05:41 (1768892741) - departure time must be equal to or greater than arrival time
