I have most of what I needed to reformat and expand/explain in the nationwide railroad DB.http://www.radioreference.com/apps/db/?aid=7747
Please take special note of the three sets of radio channels.
The middle splinter channels are almost never used and was essentially incorporated into the NXDN lineup but retains a AAR channel plan for now.
When hearing NXDN transmission, but aware they are in the ultra narrow 6.25 deviation (not 25 or 12.5 wide/narrow). This will be important when decoding and finding the correct radio channel as many commercial scanners are not very selective at this point.
This is VERY important in submitting information to the database.
PTC channels will be generally location specific and will be kept in the nationwide database. There is going to by just a sliver of spectrum used, and really no sense in putting it in the state listings as its data only. Should things take a completely different direction I'll revisit the issue (this goes with the existing ATCS section which still needs a little help).
EOT's (NS and AAR) is under the nationwide listing and will not be listed at the state level. I did leave those as FMN so that scanners will stop on these as many people use it as a train indicator. The rest will remain as "data/telemetry" as it serves no real scanning purpose in the traditional sense for most users.
I recommend that when using RRDB aware scanners and software that you load in just the AAR 001-097 channels for scanning purposes - this will prevent falsing on the other two band plans (or until a NXDN scanner is available).
I am also in the process of updating each state to a common standard of display and information. Depending on where you are, you may have already seen some of this. My goal is to finish the western plains to the west coast in the next week or two and then finish the northeast to the southeast. After that tackle the Mississippi area states.
Texas, California and I am sure Illinois will be the last to be done due to their complexity.
Feel free to ask questions in this thread or leave comments
All state listings done so far are believe to be accurate with the most current information available. Please read the text description in the state you monitor for any state/site specific information.
As a reminder, many people overlook that the database maintains common freq's used in the US (and Canada). Please click on "database" at the top, then look for the "Nationwide Freq" tab and click on that. Some of the information in there will be updated shortly. Uniden scanners get the "nationwide" freqs from that section of the database.
