In doing a check of recent FCC licenses in Klamath County, OR, I discovered one for BNSF on 44.58 MHz: http://www.radioreference.com/apps/db/?cs=WQIY624 Does anyone here have an idea of what this might be used for? I always thought railroads were operating on VHF high with the AAR channels...

it sends data to the dispatcher from the Hi-Rail trucks to give there location
I'm gonna guess the low band system is pretty well defunct at this point given that the railroads have implemented Positive Train Control, and the adjoining ITCnet system that operates on those same channels can do the same thing the lowband system did.

It's used for multiple things actually. There's a diagram here. that shows all the stuff.
It's also still very much in use, the license for the ones near me were recently renewed and I noticed it recently this weekend when a passing locomotive set off LoBand on my closecall. I thought it was a glitch at first but also heard the dispatcher giving a high wind warning from the wayside weather station so go figure. I wonder if anyone ever made a decoding program or plugin the protocol all these years later.
Also the new emission designator for it these days is 20K0F1D
