Project layouts are a rich part of Model Railroader's history. Associate editor Cody Grivno gives you a behind-the-scenes look at the HO scale Wisconsin & Southern, the magazine's 2008 layout. In this clinic, Cody talks about the field research he and senior editor Jim Hediger conducted. Over the course of several months, the duo photographed locomotives, rolling stock, structures, and rail-served industries along the WSOR system. In addition to field research, the staff was able to learn more about the WSOR through its website, which contained a list of industries served, inbound and outbound traffic, aerial photos of select industries, and a detailed locomotive roster.

With the research complete, then managing editor (now Model Railroader Video Plus producer) David Popp designed the track plan and the staff selected industries to model. Once the layout was complete, an operating scheme was developed that provided plenty of on line action, as well as interchange with the Milwaukee, Racine & Troy.
