Hello,

does anyone know what radio frequencies are used by Union Pacific on the Roseville Sub around the Donner Pass area?

Thanks.

Isn't radio traffic there digitally encoded?

All railroad radios have been digital for a decade or more.  I believe the change from analog to digital was to reduce the bandwidth for the radio channels and thus making bandwidth available for the needed radio bandwidth to support PTC.
