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.

2021年5月27日 · Originally dressed in Amtrak’s Phase II livery, the F40PHs went on to become the workhorse of the Amtrak diesel fleet, powering both short-haul and long-distance trains from Maine and Florida to California and Washington State.

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. In fact, the F40PH was EMD’s first production passenger locomotive to use this prime mover.

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. However, the SDP40F's failure prompted Amtrak to look elsewhere for a long-haul road locomotive. In response, EMD redesigned the F40PH.

Amtrak no longer carries any F40s on its active roster, but many former Amtrak units are still running. This page provides the numbers of F40s (excluding those converted to cab-baggage vehicles) were active or otherwise saved from the scrapper's torch as …

For many years, Amtrak's EMD F40PHs were the mainstay of their fleet. From the time they began arriving, in the late 1970s and early 1980s, until just a few years ago, an F40PH could be found leading almost any Amtrak train in the country. In fact, many commuter railroads adopted the F40PH design, and continue to operate their units to this day.

In 1977, Amtrak returned 40 SDP40Fs to EMD, which then repurposed components, including the prime movers, into the frames of F40PH units. These refurbished engines, known as F40PHRs, were essentially the same as the newly manufactured F40PHs, but with upgrades like a larger fuel tank and a more robust HEP generator.

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 …

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. The F40PH also found widespread use on commuter railroads in the United States and with VIA Rail in Canada.

With a total of 210 units built for Amtrak, and dozens more for commuter agencies, the F40PH became the face of modern passenger railroading and remained so for over 20 years.
