I've seen this photo in a private collection (I'm pretty sure he has the original negatives - I think they were among the Clinton Scott negatives that sold on eBay about 13 years ago) along with another photo showing the other side of the same train in the same spot. In that photo, you can see that the locomotive was DL&G 206 (a Cooke 2-8-0) with a combine, two boxcar, and a string of loaded gons. Between the McConnell stack and DL&G lettering, the photos were probably taken in the mid to late1890s. The number 206 is also legible on his copy of this photo - on the rear tender flair.
