These cars are sold as kits, with each kit providing the basics for three cars - pewter bodies, #1 log bunkers, #2 log bunkers, brake lines, Queen posts, decals, and brass etched brake wheels. Trucks, couplers, brass wire and silver bead "turnbuckles" are not included.
Beginning in the late 1920s, the Northern Pacific Railway owned over 2400 of these steel center silled logging cars. They served system wide, and were not uncommon on other connecting roads. They hauled big timber from western states, and could be used for telephone poles and trestle piles.
