I can’t say when this photo was taken but I’ll make the assumption was done in the late 1870’s, judging by the clothing of one of the individuals pictured. I’m not sure either where this picture was taken. What intrigues me is the round structure to the left and the tower in the background. I have never seen a round rail yard structure like this before with so many slot doors. Was this some sort of elaborate switchman’s shanty? The tower in the background is clearly for an observation post of some kind. With the large weather vane on top, I’m wondering if this tower has anything to do with connecting ferry service or may not be related to the yard at all.
