Thanks to Mr. Newman, I was given a heads up that G521 was about to get on the Cartersville Subdivision heading to Rockmart. Considering this was A) a unit train on the Cartersville Sub & B) a rare afternoon run on the sub with clear skies, meaning the train would be well lit up by the sun, I diverted from heading home & managed to get ahead of them in Stilesboro. Here, we see the train east of Taylorsville with the exhaust towers of Plant Bowen in the background.
