As a prototype, the SD40-2 was the most popular second-generation diesel with sales of over 3000 in the U.S. and more than 700 in Canada. There were many variations of this popular diesel because of the long production run, with Early units representing a pre-1990 appearance and Mid Production units depicting later runs of locomotives.
