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

❌1,780 errors, 5,447 warnings

Many validation errors indicate that the GTFS-RT identifiers do not match the GTFS identifiers.

Validation carried out using the current GTFS file and the GTFS-RT the 2026-07-30 at 09:06 Europe/Paris using the MobilityData GTFS-RT validator.

GTFS-rt stop_id does not exist in GTFS data E011 288 errors

All stop_ids referenced in GTFS-rt feeds must exist in GTFS stops.txt

Sample errors

Sequential stop_time_update times are not increasing E022 74 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 17894599 stop_sequence 4 arrival_time 09:10:24 (1785395424) is less than previous stop arrival_time 09:10:28 (1785395428) - times must increase between two sequential stops
trip_id 17894599 stop_sequence 4 arrival_time 09:10:24 (1785395424) is less than previous stop departure_time 09:10:28 (1785395428) - times must increase between two sequential stops
trip_id 17894599 stop_sequence 4 departure_time 09:10:24 (1785395424) is less than previous stop departure_time 09:10:28 (1785395428) - times must increase between two sequential stops
trip_id 17894599 stop_sequence 4 departure_time 09:10:24 (1785395424) is less than previous stop arrival_time 09:10:28 (1785395428) - times must increase between two sequential stops
trip_id 17902130 stop_sequence 2 arrival_time 09:07:42 (1785395262) is less than previous stop arrival_time 09:07:44 (1785395264) - 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 17857561 stop_sequence 0 departure_time 00:02:31 (1785362551) is less than the same stop arrival_time 23:55:47 (1785448547) - departure time must be equal to or greater than arrival time
