The bagasse that wasn't used as boiler fuel was shipped by rail after being baled into cubes roughly three feet on a side.  In Louisiana, the destination was a Johns-Manville plant in Harvey, LA, a suburb of New Orleans.  The plant converted the bagasse after grinding it into a rough cardboard like product under the brand name Celotex.  It was used as interior paneling for both walls and ceilings.  The rail move was in gons that were on their last legs, sprung sidewalls and end walls due to overloading and not uncommon were gons with bowed centersills from being grossly overloaded.  My first job on a Class I railroad was switching the Johns-Manville plant in 1973.
