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 .

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.

National Railroad Passenger Corporation (Amtrak) 90200-90413 are Non-Powered Control Units (NPCU). In the late 1990s, Amtrak was retiring their EMD F40PH locomotives with the arrival of new Genesis locomotives. However, the bodies and frames on many units were still usable. 22 units were refurbished by removing the prime mover, traction motors ...

With the exception of units that have been converted to "Non-Powered Cab Units" or "NPCU's" for use in Push-Pull Service on certain trains, none of these units remain in regular service today. The NPCU's were renumbered with 90 then the original unit number, example: F40PHR #251 is now NPCU #90251.

2024年11月4日 · Amtrak NPCU 'Cabbage' locomotives: While officially called NPCU's (Non-Powered-Control-Unit) by Amtrak, these earned the nickname 'cabbage car' for its dual use cab car/baggage car design. Amtrak has been using unpowered F40PH locomotives for decades in various corridors across the country.

F40PH 406 was removed from storage in 2011 after being dormant for almost 10 years. It was converted into an NPCU and was equipped with an HEP generator to provide power to the 40th Anniversary Exhibit Train. Unlike many NPCUs on Amtrak, this unit retains its original road number and Phase-III livery.

2010年12月17日 · The NPCU or Non-powered Control Units are control cars used by Amtrak that are modified from surplus EMD F40PH locomotives. A control car is a generic term for a non-powered railroad vehicle that can control operation of a train from the end opposite to the position of the locomotive.

Sadly, the once-commonplace F40s have all been retired, though some have been converted to cab-baggage Non-Powered Control Units (NPCUs). These units can be found at the rear end of many Midwestern trains, as well as in Downeaster service between Boston, MA and Portland, ME.

The Rapido Amtrak NPCU is not just our F40 model with a few bells and whistles added. We have tooled up a completely new body based on a common Phase 1 NPCU design. It features operating ditch lights, accurate enlarged marker lights, supplementary air reservoirs, K5LA horn, and other accurate NPCU details. Order deadline September 26th, 2016.
