Catskill Mountain Railroad radio freq?

Does anybody know for sure what freqency is used on the Catskill RR ?? I plan on voluntering this spring and want to be prepared .

Here's what I found:

Catskill Mountain
160.530 -- [AAR channel 28] -- mow
160.365 -- [AAR channel 17] -- road

I've also got this one for DURR:

Delaware & Ulster 161.385 -- general

I don't know how up to date they are and how often they use radios outside of train operations.

The frequencies alone are fine if you only intend to listen in with a scanner. However, if you want to bring a two way radio to communicate with the other radio users, you will need the "PL" tones that they use also. Otherwise their radios won't "hear" yours. On this subject, do they allow and/or, encourage those of us who have programmable commercial radios to bring them if we volunteer?
