I scanned all seven of these Progressive Rail frequencies today. I am less than a quarter mile from their tracks. There was absolutely NO activity recorded. I am listening with an external antenna and able to receive UPRR.

Is it possible there were zero trains in a given day from them? (They are small.)

If there were trains, is it possible the track warrant was issued by a means other than voice? (Digital?) Do track warrants have to be issued over the radio?

At what point does a railroad need defect detectors? Is it over a certain amount of track mileage? If so, what distance is that?
