St. Louis & Southwestern Railway, recognized by its SSW reporting mark and commonly nicknamed the Cotton Belt, was founded in the late 19th century to connect the Midwest with the southern United States while providing both freight and passenger service. Passenger trains such as the Cotton Belt Express continue to make Cotton Belt trains for sale especially popular with collectors and model railroaders focused on southern freight operations and regional railroading.
SSW locomotives, freight cars, and passenger equipment remain a favorite for layouts featuring cotton traffic, agricultural freight routes, and diesel-era rail operations across the South and Southwest. These railroad models are commonly added to model trains centered on classic American freight transportation and historic regional railroads.
