The SD80MAC is a 5000 horsepower C-C diesel-electric locomotive. The SD80MAC uses a 20 cylinder version of EMD's 710G prime mover,formally known as the V-20 710G3B-ES and is the first diesel locomotive to use a 20-cylinder engine since the SD45/SD45-2. The SD80MAC introduced a wide radiator housing similar to GE locomotives and the placement of dynamic brakes at the rear of the locomotive. Key spotting difference between the SD80MAC and SD90MAC include: no external rear sandbox on the 90MAC, rear number boards, and the placement of the front numberboards (above the cab windows on the SD80MAC, on the nose on most SD90MACs). The SD80MAC also has recessed red marker lights in the nose, an identifying feature unique to Conrail locomotives, although NS has removed the lights on most of their former Conrail engines.
As with all Select decoders there are also 16 separate horns, 2 separate brake squeals, and 2 bells included on this one sound profile! All changeable using CV48
