Si può far risalire l'origine delle valutazioni al documento "''History of Railroads and Canals in the United States''" (Storia finanziaria delle ferrovie e dei canali degli Stati Uniti), pubblicato da [[Henry Varnum Poor]] nel [[1860]], contenente un dettagliato resoconto delle informazioni operative e finanziarie di tutte le compagnie ferroviarie attive negli [[Stati Uniti]].
