When 844 visited OK in 2007 for the state centennial, I found them on the UP road channels for whatever sub they were occupying. All you should need to know is where they are coming from to be able to identify which sub they are on for that segment. Here's a link to find 4014 on its current journey:

At this moment as I post, 4014 is stopped near the West Chicago PD, just southwest of the Metra West Chicago station. I'd check the Aurora or Mendota Subdivision road channels.
