Having grown up a mile or so from the end of the O&W in Scranton, I'll take Firewood's comments seriously
As I walked to Junior High School, I crossed the D&H mainline and Green Ridge yard, either by a bridge or under the viaduct depending on my route. I crossed the O&W line next to the Lackawanna River which at this point was still being used occasionally by the DL&W (actually probably the EL by then). I do remember seeing EL switchers occasionally (although not frequently enough). The D&H was another matter - There was always something active in the yard and roundhouse.
Thirty years later, my in-laws moved from Yonkers to Napanoch, NY, so I had time to explore the O&W.
My parents said that we had visited Kerhonkson, NY the summer before the O&W shut down and thought they had a picture of me next to an O&W train, but never found it. I would have been too young to remember.
I do not think I appreciated the railroad heaven Scranton was in the 50s and early 60s. (and also the multiple trains stores there.) To walk to High School, I had to cross the D&H, DL&W, and Erie.
Our church was just behind the Jersey Central and I remember getting getting reprimanded by the priest when the other Altar Boy and I went to look at trains from the sacristy porch during the homily making the excuse the the censor need a new charcoal.
Those were the days - Happy Thanksgiving
