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.
