- The EMD SD90MAC is a model of 6,000 hp (4,470 kW) C-C diesel-electric locomotive produced by General Motors Electro-Motive Division. It is, with the SD80MAC, one of the largest single-engined locomotives produced by EMD, surpassed only by the dual-engined DDA40X. The SD9043MAC is the 4,300 hp (3,210 kW) variant, using a 16-cylinder 710G engine instead of the H-engine, which was originally intended as a temporary alternative while EMD tried to solve the H-engine's issues. However, the accompanying upgrade program was never utilized by its customers. The SD90MAC's features include radial steering trucks with AC traction motors and an isolated safety cab which is mounted on shock absorbers to lessen vibrations in the cab. The SD90MAC, like the SD80MAC, SD70ACe, and SD70M-2, has a wide radiator section, nearly the entire width of the locomotive, which along with their size makes them easy to spot. As of 2019, some SD90MACs are still in service on the Union Pacific. Norfolk Southern had rostered 110 SD90MAC locomotives purchased or traded from Union Pacific or the CIT Group respectively, that have now all been rebuilt as EMD SD70ACU locomotives. Canadian Pacific has also opted to convert their small fleet of long-stored SD90MACs into SD70ACUs as well. (en)
- EMD SD90MACは、GM-EMDによって開発された6000馬力(4470kW)級の電気式ディーゼル機関車である。自己操舵機構を備えた3軸台車により軸配置をC-Cとし、交流電動機によって駆動する。また、独立型運転席に運転席への衝撃を抑制するための衝撃吸収装置を組み込み、衝突安全性を強化している。SD80MACやEMD SD70ACe、EMD SD70M-2と同様に、SD90MACもまた車幅一杯まで拡大された大型ラジエータを外観上の特徴としている。 (ja)
- SD90MAC型柴油机车是美国易安迪（EMD）于1990年代中期推出的大功率柴油机车车型，与SD80MAC型机车属于同一系列，为同一技术平台上开发的产品，两者除了装用不同功率等级的柴油机外，其他结构部分完全相同。 SD90MAC型柴油机车采用模块化设计，可以采用不同功率等级的柴油—发电机组，该型机车有两种基本类型，包括采用16-710 G3B型4300马力柴油机的SD90/4300MAC型机车，以及采用16-265H型6000马力柴油机的SD90MAC-H型机车。机车采用交—直—交流电传动，电传动系统由易安迪与西门子公司共同开发，应用了GTO牵引变流器（4500V/3000A）、三相异步牵引电动机、“Sibas 16”微机控制系统。走行部采用易安迪公司的HTCR-II型无摇枕径向转向架。 (zh)
