I remember when I caught this. They passed my house on NS 224 (when it terminated at Kansas City, MO) and I knew I had to see them. They looked rare, and I looked on Heritage Units, and then they were tracked units. PRLX 6003 was removed later on, but it was a pretty cool catch. I just saw the photos on my dads gallery. I made him send me them. I did have the photos on Heritage units, but I deleted them because I didnt have a subscription. I could only post 10 photos.
