I'd say General Motors was guilty of a little false advertising there.  They infer the tractive effort to be 25% of engine weight, while the industry standards for first and second generation diesels was only 20% of engine weight.  Interesting??   ???  / Ron

Baldwin-Lima Hamilton also used a 25% adhesion factor in their diesel locomotive publications.
