An observation tower in the railyards at the Mid-Continent Railway Museum, an outdoor, "living museum" and operating railroad that has (as of 2016) operated since 1963 in North Freedom, Wisconsin. The museum re-creates "short-line" railroad town life during the “Golden Age of Railroading” in the United States during the early to mid-20th Century with operating trains, educational exhibits, and displays of restored rolling stock.
