SD70MAC Diesel Locomotive
Prototype Information
The SD70MAC uses three phase AC traction motors. Production of the model commenced in 1993, competing against the GE Dash 9-44CW. The majority of SD70MAC models were produced with the 4,000 horsepower (3,000 kW) EMD 710 prime mover while later units are rated at 4,300 horsepower (3,200 kW) and feature EMD SD45-style flared radiators. Starting in 1993, the Alaska Railroad ordered SD70MACs with head-end power to make them suitable for both freight and passenger service; no other railroad ordered this variant. Due to the Alaska Railroad’s satisfaction with these locomotives, they specially ordered additional models after EMD had transitioned production to the SD70ACe.The last order of Alaska Railroad SD70MACs was built/delivered in late 2007. The trucks were replaced with HTCR-4, instead of HTCR-I on former model.
The SD70MAC is no longer produced due to EPA regulations, and was replaced by the SD70ACe in 2004. In total, 1,109 SD70MACs were produced.
