In a bold move, the Alaska Railroad Corporation placed an order for 16 SD70MACs at $1.9 million each (which included a three year warranty).  These AC powered locomotives are Distributed Power Units (DPUs) and use ICE technology.  The railroad kept with its numbering scheme and these whopping 4,000 horsepower units were numbered 4001-4016.  The following is a few of the production photos.
