What ever became of the SD89MAC. EMD built one, GM 92, but nothing else has been said about it.
A little help Please[%-)] but I believe that the design evolved into the SD70M-2.
But the SD89MAC had a 265H engine underthe hood.
I think it is the same exact carbody as the SD70ACe though.
The SD89MAC was originally designed to be EMD’s Tier II locomotive offering. But reliability problems with the 265H set it back so I guess EMD was forced to use the 710 instead. Its basically a 12 cylinder version of the SD90MAC-H II. The SD70ACe and SD70M-2, although 6 feet shorter, share the same style carbody as the SD89MAC and SD90MAC-H II.
