- An EMD SD40A is a six-axle diesel-electric locomotive built by General Motors Electro-Motive Division between 1969 and 1970. 18 examples of this locomotive were built exclusively for the Illinois Central Railroad. The SD40A was basically an SD40 built on an SDP45 frame. The longer SDP45 frame allowed for a larger, 5000 gallon fuel tank. This locomotive is powered by a sixteen-cylinder EMD 645E3 diesel engine, which could provide 3,000 horsepower (2,240 kW). Illinois Central Railroad used the SD40A as a long-range road-switcher, utilizing the larger fuel tank found on the SDP45. The Soo Line Railroad eventually acquired five of these units and as of 2005 they are out of service. Six other units (IC 6011, and 6013-6018) remain in service under Illinois Central, which is now a subsidiary of Canadian National Railway (en)
- SD40A型柴油机车是美国通用汽车易安迪公司（GM-EMD）在1969年推出的一款柴油机车，它是在SD40、SDP45型柴油机车基础上发展而来的干线货运用柴油机车。该型机车实际上相当于采用SDP45型柴油机车底架的SD40型柴油机车，特点是具有较长的车体底架和较大的燃油储备量，使燃油箱容量由SD40型柴油机车的3,000，提升至SD40A型柴油机车的5,000美制加仑。伊利诺伊中央铁路是SD40A型柴油机车的唯一买家，该公司于1969年8月向易安迪订购了18台机车，以满足一次加油来往芝加哥和肯塔基州的需要；后来向伊利诺伊中央铁路购置了其中5台机车。 SD40A型柴油机车是干线货运用的六轴柴油机车，采用单司机室、底架承载结构、双侧外走廊的罩式车体，车体上部自前向后由电气室、司机室、动力室、冷却室四部分组成。机车走行部为两台“”三轴转向架，采用、橡胶摩擦减振器、两系弹簧悬挂装置（一系为轴箱螺旋圆弹簧，二系为摇枕螺旋弹簧）、心盘牵引装置、双侧闸瓦制动。动力装置为一台3000马力、、二冲程、水冷式、涡轮增压的16-645E3型柴油机。传动系统采用交—直流电传动，柴油机输出轴通过联轴器驱动一台AR10型交流发电机，发出的交流电通过大功率硅整流装置转换为直流电，然后供给六台D77型直流牵引电动机。 (zh)
