Stops Missing from Static GTFS Data

[Michael]

Hi,

I am seeing some stop IDs returned from the Realtime GTFS feed that are not in the Static GTFS files. For example, from the feed from https://api-endpoint.mta.info/Dataservice/mtagtfsfeeds/nyct%2Fgtfs-nqrw (attached below), stop ID R60N is not in the regular or supplemented static GTFS files.

Is this expected?

Thanks
