Boxcar, 36 Foot, Wood Truss

History: Boxcars in the early 20th century frequently featured a "Truss-Rod" design. The purpose of truss rods was to prevent the railcars from sagging in the middle by the use of turnbuckles in the center of the truss rods for tightening. Due to the limitations of the materials available at the time, there was a tendency for the railcars body to sag in the middle, between the trucks. Truss rods were designed to prevent this. They have the same purpose as I beams or channel beams do in more modern equipment; or, the unitized body of automobiles do today. They give strength in the direction needed to support the load placed on the car.
