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

❌41 errors, 107 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-05-02 at 09:09 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Sequential stop_time_update times are not increasing E022 40 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 1-729219125 stop_sequence 3 arrival_time 13:03:32 (1777719812) is equal to previous stop arrival_time 13:03:32 (1777719812) - times must increase between two sequential stops
trip_id 1-729219125 stop_sequence 3 arrival_time 13:03:32 (1777719812) is equal to previous stop departure_time 13:03:32 (1777719812) - times must increase between two sequential stops
trip_id 1-729219125 stop_sequence 3 departure_time 13:03:32 (1777719812) is equal to previous stop departure_time 13:03:32 (1777719812) - times must increase between two sequential stops
trip_id 1-729219125 stop_sequence 3 departure_time 13:03:32 (1777719812) is equal to previous stop arrival_time 13:03:32 (1777719812) - times must increase between two sequential stops
trip_id 1-729219078 stop_sequence 3 arrival_time 12:06:32 (1777716392) is equal to previous stop arrival_time 12:06:32 (1777716392) - 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 1-763232263 stop_sequence 3 departure_time 09:08:53 (1777705733) is less than the same stop arrival_time 09:08:54 (1777705734) - departure time must be equal to or greater than arrival time
