Okay, not strictly a rail car, but these trucks do have four wheels. The Northern Pacific Railroad built these trucks in the 1890s for freight car use. When NP retired this type of truck, Polson Lumber purchased a number of them for use under camp cars. These trucks last saw service under camp cars at Rayonier's Camp 14.
 
These swing motion archbar style trucks are made of wood and steel. Much of the metalwork is original. Some metal components were replicated using originals as patterns. All the wood components were replicated with reclaimed old growth lumber using original pieces as templates.
