Abstract
Bulkhead supports (18) are integrally connected to opposite side portions of a filament wound hopper car body (16). The bulkhead supports include longitudinally spaced extensions (20, 22) extending inwardly from the car body sides. The transverse bulkheads (14) are located within the extensions on either side of the car with longitudinal clearance (31). Resilient bulkhead cushioning members (32) are located between the bulkhead and each extension. The resilient bulkhead cushioning members extend only a short distance transversely to reduce or substantially eliminate the introduction of bending moments into the car body sides when the transverse bulkheads are subjected to lading loads.
