Anyone know a good website to look up railroad terms? I monitor the BNSF frequencies in Aurora, Illinois, at 161.100 (Aurora sub) and the 161.385 channel from Aurora to Galesburg. I always hear the terms "z" train and "brick gal" (I know I'm not hearing that right). Also trying to find a site that has mileposts on it for the train lines, especially BNSF in Illinois. When they give a milepost on the radio, I can then figure out where its at.
