  • Unit train coal car tension strips to prevent car body from twist
    Patent number: 4024821
    Abstract: A gondola type railway car including a pair of laterally crossed elongated braces at each end of the car which couple the car corner caps to the car floor. Each brace extends downwardly and longitudinally inward and substantially across the car. The braces restrain lateral and longitudinal deflection of the car walls and thereby substantially reduce fatigue and fracture of the corner caps and walls. These braces not only effectively oppose the loads imposed upon the walls, but also do not obstruct the functionality of the car and do not materially encroach upon the usable space.
