Went for a hike exploring the Brooklyn Cooperage logging railroad line into Everton. They pulled the tracks up in the 1920's, so it hasn't been so very many years. I found the location of the curve at Everton. The railroad is drawn as crossing the St. Regis River and recrossing it a short distance thereafter. That's certainly possible. There's not too much room between the road and the river at that point. Neither, though, did I see any sign of bridge abutments. If it was a wooden trestle bridge, it may not have had abutments.
Also found evidence of a side track north from the curve. Tie impressions, and grading. If it existed at all, it was probably just for one year, while they were logging in the area. Some time in the late 1980's I saw evidence of ties.
Further out on the rail line, it crosses Mile Brook. You can still see some remains in the wetland here: .
I hiked north along the railbed, and found another branch crossing Mile Brook. The line to the left continues northwards. The line to the right is still used as a path across the wetland: .
The best part, though, is that I found rails!. I have no idea why a pair of rails would have been left behind: . This wasn't the last place that Brooklyn Cooperage had a logging railroad, so something must have prevented them from removing those rails.
Kept walking out on the railbed. Except for a few muddy places where some vehicle dug nasty holes at some time in the past, the railbed is still in reasonable condition. I think I found the end of the northwest branch, because there's no sign of the railbed past that point.
