HO G2 SD70ACe with DCC & Sound, BNSF #8401
Selected Store
BNSF NOTES:
The lowest-numbered SD70ACes on the BNSF roster (and some of the newest), these units were built with 6-step walkways instead of 5 steps which had been standard in earlier production runs. Equipped with BNSF-style PTC antennas, they will be right at home on any late era BNSF roster.
Overview
In order to meet stricter diesel locomotive emissions standards imposed by EPA Tier 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 produces AC 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, specifically the SD90MAC-H PHII. Similar features include the nose shape, 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.
