May 10, 2016 – A Paducah and Louisville Railway DPU coal train rounds the loop at the Calvert City Loadout at Calvert City, Kentucky. I think this is the first time I can recall finding a PAL train with DPU units. It had four on the front and four on the rear of the train as it moved through the loop. – Tech Info: 1/1250 | f/5 | ISO 140 | Lens: Sigma 24-70 @ 70mm on a Nikon D800 shot and processed in RAW.
