The more fuel efficient 12 cylinder with the addition of a third turbocharger, being re-named instead of the 265mm cylinder bore to the 1,010 cubic inch displacement, became the 1010J motor used in today’s Tier-4 locomotives.īeing built from many of the same components and configurations as an SD90MAC, only a few modifications were required for Athearn to accurately depict this unique locomotive and join the stable of SD90 derivatives Athearn is already offering.

The SD89MAC was EMDs planned replacement for aging SD70s and the technology contained within evolved into the SD70ACe-T4.ĮMD historical will subtract one digit from a model number to represent a 12-cylinder version of that model. In the mid 60’s C&O adopted a new simplified paint scheme with the large C&O initials on the long.
The SD60MAC refined alternating current used in the popular SD70MAC. These units were the backbone of the fleet, used on both road trains as well as local service. The SD45X was a test bed of the Dash 2 electronics.
While ultimately unsuccessful in sales, these models did advance technology. There have also been rare models that were built and tested, but resulted in barely, if any orders like the SD45X, SD60MAC, and this model, the SD89MAC. Through its history EMD has also designed many models that never left the drafting board with notable examples being the SD30, GP50T, and DD40A. EMD has built many well known and iconic locomotives like the GP7 and SD40-2.
