I'm most curious about that white-painted structure behind the depot which also looks to be of railroad design, but no longer in railroad use. The doors and boarded over windows don't look right for a freight station. Did another road also have a passenger station here?

Given that the previous photo is clearly Broadway in Nanticoke, that is most likely the PRR Nanticoke station (humble as it is) with Nanticoke listed on PRR timetables as late as 1960 on its connecting coach service to Sunbury.
