Abstract: A railway car underframe includes a center sill having a central section and opposite end sections. The sill includes spaced vertical walls, and upper and lower walls which are slotted in registry the length of the central section, and which form in cross section a spaced I-beam construction. The construction provides a sill having high torsional flexibility which is necessary to accommodate the railway car to track conditions tending to derail the car when single axle suspensions with two wheels are utilized. The sill also includes a separator in the form of a channel which includes flanges at its sides which are secured to the vertical walls of the sill. The separator extends substantially the length of the slots and is effective to resist lateral forces tending to buckle or permanently deform the sill during operation, while not adversely affecting the high torsional flexibility which is required in the sill structure. The railway car further includes a cargo or load bearer construction having cantilevered cross bearer members which include vertical webs with upper and lower flanges projecting outwardly from the sill. The cross bearers engaged with the central portion of the sill are interconnected by straps extending through the sill. A tie member connects the lower I-beam portions of the sill to permit longitudinal displacement of the lower I-beam portion relative to each other in a limited manner thereby maintaining the required torsional flexibility.

Abstract: A modular center filler and center plate may be constructed as a unit away from the car and adapted for connection to the center sill webs of a railway vehicle. The center filler has a thick bottom plate which extends beneath the center sill and has pairs of interconnected longitudinal and transverse sill reinforcing plates arranged in a double I-beam manner. The center plate has longitudinally extending attached skirts, and bevels are provided which allow the car to rock at the bevel lines. Forces transmitted through the center plate at the bevels are absorbed and distributed by the associated longitudinal plates and other bolster and center filler structural elements.

Abstract: A high volume railway gondola car particularly suited for high speed rail operations having a bracing structure extending the length of the car including a plurality of serially interconnected V-shaped trusses having laterally longitudinally downwardly convergent bracing members coupling the car walls to the underframe along the centerline of the car.
