I took this b&w photo back in 1965 with a cheap little camera. This was before I even knew I would actually work for C&O -- and work this agency a few times off the extra board in 1976! The "clear board east" here would have been for No 58 which was a scheduled 2nd class train in the timetable back then. I can still hear the growl of those Leslie S-5T air horns on a C&O GP9.

Here's a link to my Dropbox. (I tried using the image option on here, but didn't work for me). Below that is a link to Youtube.
