Railway freight car truck with transom
View Patent ↗A stabilized railway car truck consists of two side frames and a bolster. The bolster has laterally opposite ends, each end extending into and supported within a side frame opening on a spring group. The stabilized railway car truck also includes a transom extending into, and supported within, a side frame opening. The spring group is supported at each transom end. Each side frame includes an integrally cast transom bearing over which a transom support bearing is fitted. The pivotal decoupling of the side frame and transom eliminates track displacement irregularities from reacting at the bolster and into the vehicle.
