We test this resource download availability every hour by making an HTTP
For SIRI and SIRI Lite feeds, we perform a
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 error
Validation carried out using the current GTFS file and the GTFS-RT the 2026-10-06 at 09:13 Europe/Paris using the MobilityData GTFS-RT validator.
Errors
Sequential stop_time_update times are not increasing E022 1 error
stop_time_update arrival/departure times between sequential stops should always increase - they should never be the same or decrease.
Sample errors
- trip_id 6043592056373248:1 stop_sequence 8 arrival_time 09:12:34 (1791270754) is equal to previous stop departure_time 09:12:34 (1791270754) - times must increase between two sequential stops
