Actually, "Channel 2" is 2-frequency simplex
160.83 dispatcher base
160.245 mobile
so those are paired and you have to flip between them to hear both sides of the conversation. I seriously doubt either of those is a yard channel. For my money yard channels are BORRRRRING.
The railroads are very traditional when it comes to radio assignments. The properties that used to be part of Seaboard Air Line use AAR66 which is 161.1 MHz for the road channel, including the line from Hamlet up through Raleigh. The ACL (Atlantic Coast Line) properties like the A-line use AAR32 which is 160.59 MHz for the road channel. The former Southern Ry properties almost universally use 160.95 MHz which makes it easy to follow. The dispatcher channels are typically assigned by railroad subdivision. It's one of those things that you "just have to know".
This can really take you down the rabbit hole if you pursue it because there's so much to learn about railroads.
The
Federal Railway Administration has a site that shows you what lines run where, and usually it's even accurate.
I threw together a
CSX Dispatcher Code Table when they established regional dispatch centers around their system instead of putting all their eggs in one basket in Jacksonville, Florida.
