Abstract
Center beam railroad car having a top chord, a parallel center sill below the top chord, columns joining the top chord and center sill, and diagonal tension members connecting the upper joint between one column and the top chord to the lower joint between another column and the center sill. In one embodiment, the tension member is pivotally secured at each end to the respective upper and lower joints, preventing fatigue failure of the tension member where it is secured to the joints. In another embodiment, at least one end of the tension member is secured to a joint between one end of a column and the center sill or top chord only after the joints are defined by assembling and joining the top chord, center sill, and columns. This method allows the tension members to be installed and to function substantially without tension in the unloaded, unused car and to accept tension loads when the car is loaded and operated.
