EMD SD70ACe Modern Diesel Power

The prototype EMD SD70ACe was developed to meet stricter EPA Tier II diesel locomotive emissions standards while delivering the power required for demanding freight service. The SD70ACe is powered by a 16-cylinder diesel engine rated at approximately 4,300 horsepower and uses AC traction technology for heavy mainline operation. 

The SD70ACe's distinctive profile incorporates a full-height nose door, rectangular windshields, large flared radiators with twin fans, dynamic brake equipment positioned toward the rear of the long hood, and prominent inverter equipment behind the cab. These characteristics helped make the SD70ACe one of the signature EMD freight locomotives of the modern railroad era. :contentReference[oaicite:6]{index=6}
