Default I am not clear about why I still hear RR comms in the clear (CSX)

I am not clear about why I still hear RR comms in the clear (CSX), when I hear they are going NXDN? TIA, rail fan noob.

If you are hearing them using analog, then they just haven't switched yet.

None of the Class 1 RRs are using NXDN for mainline operations.

You will likely hear mainline rail chatter on regular analog channels for a very, very long time.

Some shortlines are using NXDN and some Class 1's have some reported yard use on NXDN.

Bottom line, no need for a NXDN upgrade anytime soon if you want to hear the big boys of the rails.

Most every license in the RR allocation will have NXDN added eventually. This is what the AAR wants to switch to, but when is the issue. Some RR have said they are NOT going NXDN since they just bought new radios that didn't contain NXDN for narrow banding. We are going to be ordering another 200 Harris M7300 for some of our cars and they don't do NXDN. All of our licenses (MTA) now contain the NXDN emission designator, but we have no intention of ever going there on main line frequencies, as there are too many co-users of our tracks including Amtrak. We have begun to construct some NXDN support frequency repeaters (Yard and Fire Brigade) that are both analog and NXDN.
On a interesting note I just received an E-mail stating that the AAR coordinators are holding back on issuing NXDN licenses(I believe new allocations) since some co-users on those frequencies are running carrier squelch and would be annoyed at listening to the constant drone of digital. Not sure how it's all going to shake out and when the main lines would go NXDN.

There was another post about agencies adding NXDN and P-25 to their licenses at renewal, since you are going to pay for a new license why not add something you might use in the future instead of having to pay for again.

As a few have stated, no one is going NXDN any time soon. I know of some yard ops that are NXDN in SoCal, and we have a Class 1 in NorCal that is NXDN full time, but beyond that...Who knows!

I just spoke to the owner of Railcom, and they plan on offering a NXDN product in addition to the TRBO product now out there. The only difference between Railcom models is the chassis in the radio will either be Motorola or Kenwood.
They are also building a new custom Railcom model for Chicago Transit, but don't have any details other than regudizing the front panel.

I really like Kenwood and NXDN, but DMR would be such a better option for efficiency and capacity.

DMR is nice

There are things you can do with analog that you can not do with digital. I can see why analog is better for main line channels and digital is better for other activties

CSX and Florida Northern Rail are still using analog - I hear them almost everyday now as the coal trains head to the power plant.

The power plant also uses an analog radio on site to coordinate the unloading of the coal cars.

By Chicago Transit, do you mean the L or Metra?

I just got off the phone with him and I forgot to ask, they are building a special firmware for use, so I should have it by tomorrow. We don't need all the AAR channels so we are getting a custom HOME channel plan with larger alpha display.
