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 error, 19 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-01-14 at 08:01 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Vehicle position outside agency coverage area E028 1 error

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 190 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

Warnings

timestamp not populated W001 1 error

Timestamps should be populated for all elements

Sample errors

vehicle_id 190 does not have a timestamp

Header timestamp is older than 65 seconds W008 1 error

The data in a GTFS-realtime feed should always be less than one minute old

Sample errors

header.timestamp is 2 min 59 sec old which is greater than the recommended age of 65 seconds

schedule_relationship not populated W009 17 errors

trip.schedule_relationship and stop_time_update.schedule_relationship should be populated

Sample errors

trip_id cbb90086-f208-4872-b7ac-e6543ab3435d does not have a schedule_relationship
trip_id b43b2498-70a7-4140-a11c-ae64c6e0f2c3 does not have a schedule_relationship
trip_id 94f0a1d2-7394-4569-bf3a-53a60a36cca4 does not have a schedule_relationship
