I am still exploring the forum as I have only recently discovered it. I am a definite fallen flag devotee growing up in northern NJ. About 1964 or 65, my parents owned the Long Valley Inn in Long Valley, NJ and I remember spending a lot of time there at the restaurant/tavern while they worked away. A frequent customer was a Mr Adderly (sp)? who happened to be an engineer on the CNJ. He took a liking to me and my brother and sure enough we got the invite to ride along one of his runs. I cannot recall where we boarded, but I believe we rolled past Pictanny Aresenal/Hercules? at one point and ended up at Green Pond Junction where we were picked up by my dad. We only took a few photos, which are now gone , but I remember the units as dark (black) in color cab units. Funny what we recall as children, but to this day I can picture in my mind the heat and noise as we were walked behind to second unit during the ride. I regret not having photos to record the experience.
At this time in High Bridge Branch ops, the engines would have still been the Baldwin Babyface units, but more than likely painted in a dingy and dark dip green paint job by then, that could have easily been mistaken as black. The N&W F units that were black didn't show up until the 70's.
All in all, what a great ride that would have been, and yes, you would have passed close to Hurcules Powder in Kenvil (you wouldn't have seen it unless your train switched it), and gone right up the middle of Piccatinny Arsenal.
