Years ago I bought a used book on-line and found an aging photograph between the pages. Thinking that it might have some value to the seller, I scanned it, did some quick color/contrast correction, and e-mailed it back to them. (Never got a reply, no “thanks, I was wondering what happened to that”, no “thanks, but I bought the book at a yard sale, no idea who those kids are” no nothing, the jerk.) While searching for different photo last night, I ran across the scan again. My guess is that there is enough information in the photo that the collective wisdom of the Dope will be able to tell me the name of the train, where it ran, and possibly where the photo was taken. (I’ve got a pretty good idea of around “when” based on the kids’ clothes.)
According to this page, the fact that this locomotive was at the OP&ER narrows down the date to between 1971 and 1989. Later photos like this one from 2000 shows the logo has been painted over and replaced with “19”. Also because in this YouTube video taken at the OP&ER, there is a similar silver passenger car in the background (visible around 0:54).
BTW, I haven’t commented back yet on the answers, but it took 24 minutes from posting to a correct identification. Not too shabby. It may still take a while for someone to chime in identifying where it is parked based on that building with the yellow “tickets” sign behind the train.
(I wouldn’t be too surprised by an eventual out of the blue bump where a newly joined poster shows up who is one of the two kids in the photo, or at least knows them.)
The “building” looks like a passenger railcar with a metal “skirt” added because it’s being used as a stationary ticket office. Which (along with the steam engine itself) smacks of a railroad museum.
