Abstract: Lading restraining bulkheads for a railway boxcar are movable on overhead tracks and floor tracks along both sides of the car. Each bulkhead has a platen supported on a frame by air bellows. The frame and platen have spring pressed detents extending into perforations of the tracks. The detents are beveled on the lading side so that a sufficient force on the platen will cam the detents open and move the platen toward the lading. This action will occur when an impact on the car causes compaction of the lading.

Abstract: A tie-down system for carrying loads, such as lumber, on the deck of a railroad car is disclosed having resiliently anchored banding providing tie-downs to secure the loads onto the deck so that a minimum travel or shifting of the loads longitudinally along the deck is obtained when the loads settle and impact forces are exerted against the car. The banding is arranged in an endless double loop over the load with the free ends of the bands positioned over the upper surface of the load for tensioning and securement. The double loop permits the banding to slip longitudinally about its anchor points thereby to provide a mechanical advantage and permitting a relatively high initial tensioning to be obtained with conventional tensioning equipment without the use of power tools. Various means are employed to reduce any pretensioning in the banding upon removal of the banding and unloading the flat car. The tie-down assembly is further designed to reduce or substantially eliminate lateral movement of the lading. The tie-down assembly comprises a resilient means for pretensioning the banding, a means for receiving the banding preferably designed to avoid stress concentrations in the banding passing therethrough, and means for providing at least some rotational movement of the tie-down assembly about its own generally vertical axis at least about 20*. Means may be provided on the car for storing the tie-down assembly when not in use. And the tie-down assembly may include means for mounting the same on the car in such a manner that upon removal of the banding therefrom, the assembly automatically assumes a stored position on the car.
