I headed down to Holly around 3:00pm to watch trains, and as soon as I got to Holly, I heard a train. I figured it was probably CN, so I drove to Fenton to catch it. I got there just before it was about to enter town.
After the CN, it was about an hour until Q321 came, with a BNSF warbonnet and a BNSF leading. I caught it at Lahring Road north of Holly.
