BNFS EMD SD70MAC "RETURN Of THE MAC" Cajon Pass
Train Simulator 2015
According to Wikipedia.org :
The SD70MAC (colloquially known as a "Mac" or a "70 Mac") is very similar to the SD70M and SD70I; the main difference being that the SD70MAC uses AC traction motors. Production of the model commenced in 1993. AC motors, while simpler and more reliable than DC motors, require expensive inverters to generate a variable-frequency AC signal, raising the locomotive's purchase cost substantially. 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. They were also offered with a head-end power generation system for passenger trains.
The SD70MAC is no longer produced due to EPA regulations and has been replaced by the SD70ACe. Over 1,500 examples of this model were produced. It was purchased by Burlington Northern Railroad (now BNSF Railway), BNSF, Conrail (units now owned by CSX), CSX, Transportación Ferroviaria Mexicana (TFM; units now owned by Kansas City Southern Railway (KCS)), and the Alaska Railroad.
