1 50 in. Diameter Roll Paper Secured with Air Bags in Cushioned Boxcars with 16 ft. Wide Double Plug Doors Approved by DAMAGE PREVENTION & FREIGHT CLAIM COMMITTEE Association of American Railroads Issued January 2015 Published by Association of American Railroads/TTCI Damage Prevention and Loading Services DOT Road Pueblo, CO (Printed in U.S.A.) 2015

2 GENERAL RULES The General Rules relating to personal safety and the safe operation of trains, contained in AAR Circular Nos. 42- K and 43-E or supplements thereto, issued by the Association of American Railroads, must be observed. These loading rules and/or practices apply to shipments transported in the USA, Canada and Mexico. The loading methods in individual closed car loading publications issued by the Damage Prevention and Loading Services Section of the Association of American Railroads are minimum standards that have been evaluated and approved. These minimum standards offer practical guidelines on the subjects covered. Since these are minimum standards, it may be necessary to supplement these methods in some instances. Securement standards in AAR closed car loading publications are intended for safe transit of the rail car from origin to destination and prevention of lading and equipment damage. These standards do not address unloading practices. This approval may be withdrawn if the loads using these methods exhibit consistent load failure during actual shipments. Loading and bracing methods not presently approved may receive consideration for approval and publication under Section II - Evaluation of New Loading and Bracing Methods and Materials for Closed Cars, Trailers or Containers of General Information Bulletin No. 2, Rules and Procedures for Testing of New Loading and Bracing Methods or Materials. Submit requests to Director Damage Prevention and Loading Services, AAR/TTCI, DOT Road, Pueblo, CO CAUTION: Car rocking motion caused by the lift equipment entering and/or exiting the rail car may cause unsupported packages or articles with a higher center of gravity to fall to the floor. Minimize access to the car. Exercise caution when inside a partially loaded car. Lift operators should stay on lift equipment, whenever possible, while inside a partially loaded car. SELECTION AND PREPARATION OF CAR It is the railroad's responsibility to supply boxcars which are clean, have sound roofs, sides and end walls, smooth floors and snug fitting doors. Any exception is cause for rejection. If the boxcar supplied is not suitable for loading and the shipper elects to load the boxcar rather than reject it, it is the shipper's responsibility to properly prepare the boxcar. The shipper has the responsibility to inspect boxcars at origin to see that they are suitable to carry lading safely and damage free to destination. It is important that boxcars are clean and free from protruding nails, brads, staples, temporary anchor plates, fragments of steel strap, old blocking etc. Some projections of lining or anchor devices may require covering with sheets of corrugated fiberboard taped in place. GENERAL 1. This loading method was tested in boxcars with 60 ft. 9 in. inside length, 9 ft. 6 in. inside width, and 16 ft. wide double plug doors. 2. Use only cushion equipped cars when employing the loading method described herein. 1

3 3. This method is approved for use only in loads of 50 in. diameter roll newsprint or printing paper utilizing air bags installed horizontally between rolls to fill lengthwise space in the doorway area. 4. Use 28 or 29 floor spot load patterns based on car width and roll diameter tolerance variations. The rolls in each end of the car may be loaded in a 2-2 offset pattern, a pattern, or some combination of the two patterns. See Illustration No 1. The load in each end of the car will end with 2 parallel rolls adjacent to each car doorpost Pattern 2-2 Offset Pattern Combined 2-2 /2-1-2 Pattern Illustration No. 1 Loading Patterns 5. When transitioning from a 2-2 offset pattern in an end of the car to the doorpost roll or stacks of rolls, use filler panels to align the doorpost rolls parallel to one another as shown in Illustration No. 2. Filler Panels: at least 2/3 s the height of the adjacent roll or stack of rolls Illustration No. 2 Filler Panels to Align Stacks Across Car Illustration No Floor Spot Loading Pattern 2

4 6. The doorway consists of 6 rolls or stacks of rolls centered in 2 rows of 3 as shown in Illustration No. 4. Use 2 mm thick rebonded rubber mats of sufficient size to cover 50% of the end of the roll, between stacks of rolls in the doorway area. Do not use mats on the floor beneath the rolls in the doorway. 7. Unitize the 4 adjacent rolls in the doorway with one type 1A, grade 5 nonmetallic strap per layer, tensioned and secured in accordance with manufacturer s instructions. 8. Use one level 4 or level 5 air bag (depending on the weight of the load) per layer of rolls to fill the remaining lengthwise space in the doorway area. Bags should be a minimum of 102 in. in length and not less than 2/3 s the width of the adjacent roll in height. The space filled should be no more than 12 in. after the air bags are inflated. Inflate air bags to 8.0 psi. Check air bags 30 minutes after inflating and reinflate to 8.0 psi as needed. 9. Do not use filler panels adjacent to air bags. If additional fillers are needed to keep the space filled by the air bag to less than 12 in., they should be positioned between the doorway stacks and the doorpost stacks. Use tape or other means to keep fillers in position. 10. Filler panels may optionally be used at car end and or sidewalls to provide roll protection from nonuniform wall surfaces or to adjust the load pattern for optimal fit to railcar dimensions. Use tape or other means to keep fillers in position. Illustration No. 4 Isometric View of Doorway Area 3
