Download availability

Learn more

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

❌8 errors, 184 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-01-22 at 08:07 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Sequential stop_time_update times are not increasing E022 8 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 1_41022555 stop_sequence 2 arrival_time 11:01:56 (1769065316) is equal to previous stop departure_time 11:01:56 (1769065316) - times must increase between two sequential stops
trip_id 1_41022555 stop_sequence 2 departure_time 11:01:56 (1769065316) is equal to previous stop departure_time 11:01:56 (1769065316) - times must increase between two sequential stops
trip_id 1_41027131 stop_sequence 13 arrival_time 10:48:31 (1769064511) is equal to previous stop arrival_time 10:48:31 (1769064511) - times must increase between two sequential stops
trip_id 1_41027131 stop_sequence 13 arrival_time 10:48:31 (1769064511) is equal to previous stop departure_time 10:48:31 (1769064511) - times must increase between two sequential stops
trip_id 1_41035389 stop_sequence 6 arrival_time 11:03:09 (1769065389) is equal to previous stop arrival_time 11:03:09 (1769065389) - times must increase between two sequential stops
