I am guessing that NO&NE is operated as a part of the NSRR.
The KFF630 FCC license expired on June 8, 2014.
There should be other FCC licenses issued for remote bases along the NO&NE trackage, and in the yards.
It looks to me that NO&NE is trying to harmonize radio frequency usage with the channel usage on the other parts of the NS in the southern US.
160.95 (AAR 56) is the SIMPLEX ROAD channel used on the NS outside of yards, and is called Channel 1.
160.245 (AAR 09) is the Dispatch out Frequency.
160.830 (AAR 48) is the Train to dispatch Frequency.
160.245 (AAR 09) and 160.830 (AAR 48) are used together in SEMI-DUPLEX mode,(one way at a time, not both channels talking and receiving at the same time). Together they are called Channel 2.
161.490 is used as a Tower frequency in many yards. (i.e> the "Dispatch" channel for controlling movements inside yards) (Hostlers, and other personell who have to be in, and moving about the yard, but are not train crews )
Look for other AAR channels being put into use at NO&NE yards.
Usually there are other AAR channels being used inside yards, ( pin Pullers at the Hump, Car inspectors making up train connections,
remote train controller talk back, yard maitenance personell, etc.)
