The EMD SD80MAC was a 5,000 horsepower (3.7 MW) C-C diesel-electric locomotive first produced in 1995 and in service until February 2020. It was powered by a 20-cylinder version of EMD's 710G prime mover, and was the second diesel locomotive by GM-EMD to use a V20 engine, since EMD's SD45 series. It introduced a wide radiator housing similar to GE Transportation locomotives and the placement of dynamic brakes at the rear of the locomotive, which is a quieter location, features that were incorporated into the SD90MAC and SD70ACe models. Key spotting differences between the SD80MAC and SD90MAC include no external rear sandbox on the SD90MAC, no rear lighted number boards on the SD90MAC, and the placement of the front number boards (above the cab windows on the SD80MAC, on the nose on most SD90MACs). The SD80MAC also had recessed red marker lights in the nose, an identifying feature unique to Conrail (CR) locomotives, although Norfolk Southern (NS) had removed the lights on most of their former Conrail engines. All 30 SD80MAC units built were delivered to Conrail, and the 28 production units were completed, tested, and painted at the former Pennsylvania Railroad shops in Altoona, Pennsylvania. Prior to the 1995 merger with Union Pacific, Chicago and North Western Railway placed an order of 15 locomotives. Canadian Pacific placed an order as well but it was changed to SD90MACs. Conrail planned a second order of SD80MACs, but its new owners changed the order to SD70s and SD70MACs, all of which would be built at the Juniata Shops in Altoona. Vale Mining of Brazil ordered a set of seven updated locomotives designated as the SD80ACe model. These locomotives feature Tier 1 compliant 20-710G3C-ES engines, with 5,300 hp (4.0 MW) at 950 RPM. The design is currently for export only, and these specific...
