This project takes a look at the iconic BN/BNSF SD70MAC in the original cream and green paint scheme. These locomotives, in the 9400 to 9837 number series, have been a fixture on BN/BNSF coal trains and heavy tonnage trains for over 25 years. Featuring over 300 photographs, we see the MACs throughout their entire service lives. For fans of these locomotives to the model railroader wanting reference material for their modeling projects, the Executive MACs will be a valuable resource to add to their libraries.
