Well said. I'm glad that I had an interest in railroad structures when I started shooting pictures as a teen in the mid-1970s. There were a lot that still stood back then and I carried forth throughout the decades. Few survive these days. Catwaba, SC was a neat spot. This 10/31/1992 shot shows the layout, with a steep grade rising from the SAL to the SOU. The SOU's line crosses on the bridge in the distance. There was once an interchange yard on the grade. That interchange track is gone today, but some overturned lengths of rail can still be found in the woodland.
