I live in Louisville Kentucky and there are Norfolk Southern and CSX tracks near me, I have all of the NS and CSX frequencies programmed in on my scanner and can hear the CSX detectors sometimes but the with the NS detectors I have never heard a detector. I have confirmed with a railroad employee my moms friend that the Detectors broadcast on NS 160.95 Road channel 056056 and have programmed that into my scanner and still nothing. Can someone please help me on this. Thanks!
