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, 136 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2025-11-28 at 08:02 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

stop_time_update departure time is before arrival time E025 2 errors

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 1-17236061 stop_sequence 20 departure_time 17:42:00 (1764261720) is less than the same stop arrival_time 17:42:40 (1764261760) - departure time must be equal to or greater than arrival time
trip_id 1-771948888 stop_sequence 10 departure_time 17:42:00 (1764261720) is less than the same stop arrival_time 17:42:26 (1764261746) - departure time must be equal to or greater than arrival time

Warnings

vehicle_id not populated W002 45 errors

vehicle_id should be populated for TripUpdates and VehiclePositions

Sample errors

trip_id 1-235143169 does not have a vehicle_id
trip_id 1-17760360 does not have a vehicle_id
trip_id 1-17760362 does not have a vehicle_id
trip_id 1-1057096194 does not have a vehicle_id
trip_id 1-17236060 does not have a vehicle_id

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 857 min 6 sec old which is greater than the recommended age of 65 seconds

schedule_relationship not populated W009 90 errors

trip.schedule_relationship and stop_time_update.schedule_relationship should be populated

Sample errors

trip_id 1-235143169 stop_sequence 18 (and potentially more for this trip) does not have a schedule_relationship
trip_id 1-235143169 does not have a schedule_relationship
trip_id 1-17760360 stop_sequence 23 (and potentially more for this trip) does not have a schedule_relationship
trip_id 1-17760360 does not have a schedule_relationship
trip_id 1-17760362 stop_sequence 1 (and potentially more for this trip) does not have a schedule_relationship
