Driving north on NY rt. 9 towards Round Lake there are 2 RR overpass bridges. One says D&H on it and still looks active and the other one just before you enter Round Lake looks like a rail trail. What RR was that and where did that line go to?
If this is what I think it is you went under the old D & H mainline that went through Round Lake
They built a new connection to the line north which bypassed Round Lake a good many years ago so this line has been gone for a long time. Round Lake is a really nice little village and is well worth a visit. It was once a Methodist Camp Meeting site that became a village maybe in the 1960's or so. It still has a wonderful old auditorium that dates back to the 1880's with a pipe organ that dates back to 1847 and still sounds good today. When I was still working in Selkirk and lived a reasonable distance away I volunteered here and although it was work I enjoyed it very much. The community room in the village building has the name plate from the old station building.
