When shipping pulpboard rolls in cushion-equipped boxcars, more rolls can be shipped in a single railcar by using an on-side or T-Loading method. T-loading consists of loading the first layer of rolls into a railcar using an AAR approved loading pattern then adding a second layer of rolls on top, placed in bilge position. This creates a “T” like pattern with the pulpboard, as shown in the diagram below from the AAR’s publication Best Practices for Loading Roll Paper in Railcars. To secure the pulpboard, each roll on its side must have a chock placed underneath it and there must be a blocking roll at or before the doorposts at the A and B end of the railcar. Chocks used under the pulpboard must be of an appropriate height and width, whether they are built up corrugated chocks or rubber alternatives. Blocking rolls must be slightly higher than the adjacent rolls in the first layer. This can be accomplished by using a slightly taller roll or by placing risers underneath the blocking roll to increase its height. The top of the blocking roll, along with the chocks, will stop the second layer of pulpboard from rolling towards the doorway area of the railcar. When T-loading, the doorway must be loaded and secured using an AAR approved method. Shippers should advise the consignee that these loads contain two layers with rolls placed on their sides, so they are properly equipped when unloading the shipment.
T-Loading is only AAR approved for certain roll sizes and with certain commodities. Please ensure you review section 6.6 of the AAR’s Best Practices for Loading Roll Paper in Railcars to see the full guidelines and restrictions for the use of T-Loading methods.
