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

❌2 errors, 13 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-01-22 at 08:09 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Vehicle position outside agency coverage area E028 2 errors

The vehicle position should be inside the agency coverage area. This is defined as within roughly 1/8 of a mile (200 meters) of the GTFS shapes.txt data, or stops.txt locations if the GTFS feed doesn't include shapes.txt.

Sample errors

vehicle.id 54 at (0.0,0.0) is more than 1609.0 meters (1.00 mile(s)) outside entire GTFS shapes.txt coverage area - vehicle should be within area
vehicle.id 14 at (0.0,0.0) is more than 1609.0 meters (1.00 mile(s)) outside entire GTFS shapes.txt coverage area - vehicle should be within area
