I remember reading someplace they use 160.230 and 160.320 MHz, which are used by CSX, and I am sure they probably have several others frequencies they use as well.
Ok so maybe I was being lazy 160.2300 csx ch 8. Used for most all regular talk and the defect detector also uses this. 160.5300 csx ch 28, yard, track, around west Cumbo.
160.7850 csx ch 45 some use. 160.9200 ch 54 Winchester & Western little use, if any? 161.5200 csx ch 94, you will hear the dispatcher out of Jacksonville FL. on this frequency.
