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

❌250 errors, 73 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2025-11-02 at 08:01 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Sequential stop_time_update times are not increasing E022 114 errors

stop_time_update arrival/departure times between sequential stops should always increase - they should never be the same or decrease.

timestamp is in the future E050 58 errors

All timestamps must be less than the current time

Sample errors

trip_id 5456407 timestamp 08:05:48 (1762067148) is 4 min 38 sec greater than 08:01:09 (1762066869302) - the current time in milliseconds
