Page "hobbies" Paragraph 1089

Lumber dealers and lumber manufacturers have agreed on a standard unit for unitized shipments -- 48'' '' wide by a nominal 30'' '' high ( or six McCracken packets 24'' '' wide by nominal 7'' '' high ).

These units make it easy to load as much as 48,000 bd/ft ( say 120,000 lb in a 50' box car ) much more than the average for loose-loaded cars.
