The EMD F40PH is a four-axle 3,000–3,200 hp (2.2–2.4 MW) B-B diesel-electric locomotive built by General Motors Electro-Motive Division in several variants from 1975 to 1992. Intended for use on Amtrak 's short-haul passenger routes, it became the backbone of Amtrak's diesel fleet after the failure of the EMD SDP40F.

F40PH和GP40/SD40系列机车一样，装备了EMD 16-645E型16缸二冲程涡轮增压柴油机，标称功率为 3000hp（2200kw） （1985年后的批次提升到了3200hp），采用 交-直传动，四轴，AAR轴式为 B-B。 机车长度17.1m，宽3.23m，高4.76m，标准重量为 117.9t。 机车设计运行速度为103mph（166km/h），但美铁部分批次的机车通过改变齿轮比，运行速度达到了110mph（177km/h）。 F40PH的命名方式为： F ull-width cowl body, Model- 40, P …

F40PH型柴油机车是在 GP40-2型柴油机车 基础上发展而来的干线客运用的四轴柴油机车，采用单司机室、底架承载结构、双侧内走廊的棚式车体。 车体上部自前向后由司机室、电气室、动力室、冷却室四部分组成。

Built around EMD’s venerable 16-cylinder 645E3 power plant, the F40PH was rated at 3000 HP, but they featured a unique control system to allow them to provide head-end power. The F40’s alternator for the HEP was driven directly off the prime mover, and in order to supply power at the correct 480V and 60Hz, it had to run at exactly 896 RPM.

The EMD F40PH is a full cowl-bodied, 3,000 hp to 3,200 hp four-axle diesel-electric locomotive, which was originally built by Electro-Motive Division between 1975 to 1992 and was then built by Morrison-Knudsen Rail and then MPI (Motive Power Inc) in the 1990s and early 2000s.

2023年2月1日 · Amtrak F40PH locomotives are considered the standard passenger motive power for the 1980s and early 1990s. The four-axle, 3,000-hp units are mechanically identical to the much more common GP40-2 freight locomotive, which also use the 16-645E prime mover.

The EMD F40PH is synonymous with the Amtrak era of American passenger trains. Although it has been retired from Amtrak service, it operated for over 20 years and today it continues to be the motive power for commuter railroads such as VRE, MBTA, Caltrain, Metrolink, and Metra) and more all over the United States.
