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.

They have a second diesel engine, made by Cummins, that powers the head-end power (HEP) generator to provide electricity to the cars. This allows the full 3000 horsepower of the main engine to be used for tractive effort - on a regular F40, the generator can use as much as 710 HP.

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。

2025年2月26日 · Electro-Motive's F40PH series became the face of Amtrak for more than two decades. The model was originally designed to operate in commuter and short haul service.

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 …

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.

The EMD F40PH, a four-axle passenger locomotive with a power output of 3,000 to 3,200 hp, was developed by General Motors' Electro-Motive Division. This model's inception dates back to May 8, 1975, when Amtrak placed an order for the first 30 F40PH units following the unsuccessful deployment of the larger EMD SDP40F locomotives.
