The current issue of Railfan and Railroad has an exceptional article on Baltimore’s Canton RR, a modern switching line. I particularly liked the highly detailed explanation of their switching operations. The photos are superb as is Otto’s illustration. You can buy it HERE. My Barnes and Noble had it in the magazine rack.
I have a chapter (and track plan) in my most recent book 8 Track Plans for Modern Switching Layouts, on a segment of the Canton. The article sheds a lot of light on how to operate the layout.
