The SD40T-2 is a model of diesel-electric locomotive built by General Motors Electro-Motive Division in the United States. The SD40T-2 is equipped with a 16-cylinder EMD 645E3 diesel engine producing 3,000 horsepower (2,240 kW). 312 SD40T-2s were built for three railroads in the United States between April 1974 and July 1980. This locomotive and the SD45T-2 are popularly called tunnel motors, but EMD's term is SD40-2 with "cooling system modifications" because they were designed for better engine cooling in mountainous areas. The difference between this locomotive and its non-tunnel motor cousin, the SD40-2, are the radiator intakes and radiator fan grills located at the rear of the locomotive.

  • The SD40T-2 is a model of diesel-electric locomotive built by General Motors Electro-Motive Division in the United States. The SD40T-2 is equipped with a 16-cylinder EMD 645E3 diesel engine producing 3,000 horsepower (2,240 kW). 312 SD40T-2s were built for three railroads in the United States between April 1974 and July 1980.

The difference between this locomotive and its non-tunnel motor cousin, the SD40-2, are the radiator intakes and radiator fan grills located at the rear of the locomotive. This locomotive model was purchased by the Denver and Rio Grande Western Railroad, the Southern Pacific Railroad, and its subsidiary Cotton Belt. Southern Pacific's version has a 4,400-US-gallon (16,700 L; 3,660 imp gal) fuel tank and is 70 feet 8 inches (21.54 m) long. Rio Grande's version has a smaller 4,000-US-gallon (15,100 l; 3,330 imp gal) fuel tank. (en)

  • SD40T-2型柴油机车是美国通用汽车易安迪公司（GM-EMD）在1974年推出的一款电力传动柴油机车，属于易安迪Dash 2系列柴油机车产品之一。该型机车是在SD40-2型柴油机车的基础上，针对在美国西部运用的机车在夏季通过长隧道时、冷却系统散热能力明显不足的问题，参考其兄弟车型SD45T-2型柴油机车的经验改进设计而成。1974年6月至1980年7月，易安迪公司制造了312台SD40T-2型柴油机车，全部交付、南太平洋铁路及其子公司使用。 SD40T-2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，其中电气室一端称为短罩端，动力室和冷却室一端称为长罩端。与SD40-2型柴油机车相比，SD40T-2型柴油机车的车体底架延长了22英寸，并相应加大了散热器和进风口面积。机车走行部为两台易安迪，主要特点包括具有较大刚度的橡胶摇枕弹簧二系悬挂装置、牵引电动机顺置布置、大直径心盘及低位牵引装置等，具有充分利用最大的粘着重量、降低、提高牵引能力的优点。动力装置为一台3000马力的16-645E3型柴油机，这是一款、二冲程、水冷式、涡轮增压的V型柴油机，气缸直径为9-1/16英寸（230.2毫米），活塞行程为10英寸（254毫米），额定最高转速为每分钟900转。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。牵引电动机采用轴悬式驱动方式，牵引齿轮传动比为4.13（62：15）。机车设有恒功率励磁调节系统和模块化电子控制系统。 (zh)
