Hey guys...not sure how many here are into listening to Rail communications... But I found what I'd say is the *perfect* radio for this.
Kenwood TK-280.
It'll do 250 channels and will scan then all, and quite fast.
I have one that I've programmed with all 98 AAR channels.
It recieves FAR better than a scanner or ham radio ever could.
Just something to consider should you be in the market.
Programming services can be had cheap. Enquire within
