Introduced in 1966, the EMD SD40 and its family of later variations, became the best-selling diesel of all time. The SD40 and the other 1966 line-up of EMD locos featured the new 645-series prime mover, the first major engine change since 1939. The success of this diesel engine and the 3000 h.p. rating have made the SD40 family of locos the standard of American railroads. Now, over three decades since their introduction, many of these locos are still in regular mainline operation.
