In order to meet stricter diesel locomotive emissions standards imposed by
EPATier II regulations, EMD modified the SD70MAC to create the SD70ACe
and SD70M-2. Each model is powered by a 16-cylinder, 4300-horsepower
diesel engine. On the SD70M-2, the prime mover drives an alternator and
producesAC current that is rectified to DC current, which powers the traction
motors. On the SD70ACe, the DC current is then “chopped” back into AC to
power the traction motors.
Much of the external design is based on the SD90 series locomotives. Similar features include the full height nose door and rectangular windshields, the
large flared radiators with two fans, and the positioning of the dynamic brake
equipment at the rear of the long hood. In addition, the inverters were moved
from inside the long hood to a box on the walkway behind the fireman’s side
of the cab.
