Reference tables for TfNSW data. A complete list of agencies and how they are defined in each GTFS feed. **Using Complete GTFS + Real-Time GTFS feeds** The reference tables illustrates agencies that appear in multiple GTFS feeds. If you are using the Complete GTFS bundle in conjuction with the real-time GTFS feeds for each mode then you will need to filter out the Complete GTFS agencies and use the corresponding real-time agencies. **Turn Up and Go/Frequency Services** High Frequency services run to an operational timetable as per the relevant GTFS bundles, however they will adjust to headway in response to operational requirements throughout the day. Therefore we recommend ignoring the delay information passed on in GTFS-R feeds for these routes, and only showing real-time arrival/departure times to customers. **Train Run Numbers** The list of trips in the reference tables represent services that appear in both the Sydney Trains real-time feed and NSW Trains rural and regional real-time feed. If you are using both feeds, TfNSW recommends filtering out these services from the Sydney Trains feed and preferentially using the NSW Trains feed.
