CSXT will be replacing 40,000 Cross Ties in the next few weeks in Cullman County Alabama this is for those who listen to the live feed of CSXT & Norfolk Southern for Morgan County Alabama
For W9RXR: CSX mostly uses AAR 45 around here, too. I have that frequency in the yard radio (stereo feed) for the Morgan County railroad feed but I would be surprised to pick up the action in Cullman. It is a little too far away to pick up from Decatur unless conditions are right.
Here is the link to the feed if you are interested in checking it out: Decatur Area CSX and Norfolk Southern Rail Live Scanner Audio Feed
