General Rules Governing the Loading of Commodities On Open Top Cars
PREFACE
The Rules Governing The Loading of Commodities on Open Top Cars are covered under the following Sections of this manual:
Section No.Description
1General Rules (Applicable to Sections 1 to 6).
2Steel Products, Including Pipe.
3Road Grading, Road Making, and Farm Equipment Machinery.
4Miscellaneous Commodities, Including Machinery.
5Forest Products.
6 Department of Defense Materiel.
These rules have been formulated for the purpose of providing uniform, safe and economical methods of loading in open top cars, and the material specified in these rules for securing the loads are minimum requirements. All of the General Rules and the requirements for blocking and securing of loads as outlined under the individual figures are mandatory and must be used unless their omission is specified in the individual figures.
When the dimensions and kind of materials to be used for securing the load are not specified under the figures, the General Rules, Section No. 1, which are to be carefully observed in connection with all loading, will govern.
Unless otherwise specified, Shippers must implement all new figures, revisions to figures, or instructions covered by circulars within but not later than three months from the date shown on such releases. This period is to allow for the dissemination of information and to permit for depletion of securement and blocking materials that may be on hand and to provide for the procurement of new securement materials.
In the loading of such cars the hazards connected with speed, multiple track railroads, tunnels, bridges, overhead structures, electric conductors, and the necessity of protecting human life and property should be borne in mind.
These rules are based on many years of exacting studies and experiments, however, the railroads stand ready at all times to cooperate with the shippers for betterments. Suggestions made to the Secretary, Mechanical Division, Association of American Railroads, 59 E. Van Buren Street, Chicago, Illinois 60605, will be given prompt attention.
Shippers of Department of Defense materiel desiring new, revision of, or additions to the present rules or specifications, must submit such proposals to U.S. Army Transportation Engineering Agency, Military Traffic Management and Terminal Service, P. O. Box 6276, Newport News, Virginia 23606, through the appropriate channels for handling with the Mechanical Division of the Association of American Railroads.
*Unless otherwise specified in the figures the securements are shown for loads on flat cars not exceeding 60 ft. in length. When lading requires flat cars longer than 60 ft. the shipper and originating carrier are to confer as to additional secure-ments required.
When steel floored cars are furnished in lieu of wood floored cars, any floor blocking or metal anchor plates required under figures or rules to be nailed to wood floors, must be bolted to steel floors. General Rule 9 must be observed in the application of the bolts.
All floor blocking applied to control lateral movement of load on cars equipped with nailable steel flooring must extend, through the use of back-up blocking, to the sides of the car. In the case of flat cars, back-up blocking must extend to the stub stakes. This requirement does not apply to the composite or combination wood and steel type nailable flooring.
Unless otherwise provided for in the individual figures of Section Nos. 2 to 6 inclusive; when more than fifty (50) percent of top layer of multiple tiered load extends above the top of the car side or ends, side stakes must be used as provided for in General Rule 10 of Section No. 1.
Unless otherwise specified, all of the figures in Section Nos. 3, 4 or 6 covering various types of vehicles, are applicable only when vehicles are empty.
Fixed supports, brackets or other appurtenances on lading, must be of sufficient strength to safely support unit in transit, or body of same must be adequately supported for rail transportation.
*On the page where any change or revision is made to these rules and/or figures, effective September 1963, an asterisk will be placed in the margin to the left of that portion affected, to indicate the current change.
