Remarks: At first glance, I thought I was witness to a 'one-hit wonder' feat of strength as the 893 hustled 90-odd loaded coal hoppers past the Ashland station. Not quite - sister unit 804 was pitching in from the other end. I thought 804 was a DPU, until a fellow railfan explained that CSX employed crewmembers on each end to facilitate a backup move onto the Dahlgren Industrial Track.
