PERSHING TRANSPORTABILITY STUDY. FOREIGN RAILWAYS. VOLUME 3
Abstract
Foreign railcars were used in conducting rail impact tests on Pershing missile system first and second stage motor containers, XM 475 and XM 476. Data from the tests will be used in evaluating the effects of the foreign rail environment on the containers and in determining if the procedures used in restraining the containers for CONUS rail shipment would be applicable to foreign rail shipment. The CONUS rail shipment restraining arrangement evaluated during this study was basically in conformance with pages 4 and 9 of Savanna Army Depot Drawing No. 5425. Results of the study showed that the container skid bolts do not have the required structural strength to resist the dynamic loading imposed by rail impacts. The 1/2-inch-diameter bolts attaching the skid to the container experienced shear failure at impact velocities of 7 miles per hour when the container skid was not abutted flush with the forklift receptacle. The results of the study also indicated that the restraining arrangement providing transfer of shocks into the forklift receptacle rather than to the container skids is the preferred arrangement.
