Dad took this photo at Dents Run, Pa, probably in the late '20s.
The Dents Run Railroad crossed the Buffalo&Susquehanna and then crossed the West Branch of Sinnemahoning Creek, finally reaching interchange with the PRR Low Grade (seen in the background). That bridge was washed out in the Flood of '36 and that was the end of the Dents Run Railroad. The flood also ended the B&S.
My Grandad and his brother went to telegraphy school and were both tower operators on the Pennsy. C.1910 Grandad's tower was about a mile to the right of the photo and my Great Uncle's tower was a few miles further West. Grandad met his future wife at Dents Run as her mother ran the boarding house where Grandpa boarded. Great Uncle met his wife because she was a telegrapher/tower operator on the B&S and his tower and her station were situated where the two railroads were 100ft apart.
