Are you sure of these freqs? They are within the bandwidth of the current freqs, but off-center. I am not seeing anything in the FCC database for the listed freqs.

Good catch Charles. I'm also wondering where those frequencies actually came from.
Right now all areas that are outside on the IRT and IND are narrowband, 161.190 and 161.565 respectively. When you program them in your radio, you select narrow instead of wide. PL tones are still the same right now. In the future, PL tones will change on the RX and each division will have its own yard channel (same frequency, different PL tones).
No, as it is right now, all channels have the same PL tone. Once narrowbanding is completed, each divisions command center channel and trai to train channel will have its own PL on the recive side. Also there will be a Yard channel for each division, again with different PL tones.
I understand command center will time change
However for example the BMT Div has more then one control center talking to trains
Will the pl tones on the BMT Div have 7 to 8 pl tones for each line same frequency
As it stands now the channel is horrible with ever line crossing one another
So is this plan directed to eliminate the pile up communications?
