Mike: In my opinion, your posting, "questions", was mainly objective, with the exception of the last paragraph. Your statement-"Thier (CHS) lack of knowledge is what is requiring trains to be run on the edge of, or exceeding workable tonnage limits and forcing the antique equipment to be brutally abused" Mike, with all due respect, CHS is not responsible for how the engines are used in operations. That is the responsibility of Railstar. Not now nor never would we push a locomotive beyond or past what it is capable of handling. And, I would beg to differ with you on your comment that there is a "endless supply of narrow gauge locomotives....etc." Mike, this last comment is not very objective and a bit flamming and not necessary to get your point across. Education and learning is a life long process.
