Never really got into listening to railroad and aircraft on the scanner. In looking at the Kansas Railroad page here on RR, it looks like the list for the Ark City and La Junta Divisions of BNSF are pretty similar and include PBX and Sand Creek Yard frequencies. I thought the main channel around here used to be 160.65, but looks like that is no longer the case. I see K&O now has a couple of channels listed as well.
