Another locomotive pair

In addition to the Amtrak locomotives I've been constantly running in to, I have run into the same pair of Nofolk Southern locomotives THREE TIMES in the past month or so. They are GP60 #7122 and high-hood GP38-2 #5045. They've always been paired together, and have always been facing in the same direction, with the 7122 facing West, and the 5045 facing east. I ran into them the first time after filming my friend Kyle's Amtrak train headed to Chicago. The second time was heading West on a freight a few days later. The third time was on my big railfanning day on December 21 when I caught them switching the I&M interchange. The 5045 had an excellent K5LA on it.
