Railroad
[edit] Finding Specific Railroad Frequencies
A great place to start is the RRDB for your particular area. Sometimes, there is not any information to be had and this is where it can be fun!
If you live in the USA you can find all the railroad licenses in your area with a visit to the FCC's website
Next, select one of the Frequency (Range) queries and then enter M160.215 and M161.565 for the begin and end search frequencies.
For Service select Land Mobile - Private [LP]
For Radio Service select Industrial/Business Pool - Conventional [IG]
You can then download the results or search them and make a custom spreadsheet with only the fields you want and download it.
As always, be sure to submit any new information for inclusion in the RRDB!
If you don't find it here or in the database, feel free to post a message in the Railroad forum on RadioReference
[edit] VHF Frequencies
Railroad radios display the transmit and receive frequency as AAR channel numbers. For example, these numbers will be referred to over-the-air as "1616" for AAR channel 16 (160.350) or "1180" for AAR channels 11 and 80 in full duplex use (Dispatch transmits on one channel and the train transmits on the other channel).
