The '''EMD FP45''' is a [[cowl unit]] type of [[Co-Co locomotive|C-C]] [[diesel locomotive]] produced in the [[United States]] by [[Electro-Motive Diesel|General Motors Electro-Motive Division]] (EMD).  It was produced beginning in 1967 at the request of the [[Atchison, Topeka and Santa Fe Railway]], which did not want its prestigious ''[[Super Chief]]/[[El Capitan (train)|El Capitan]]'' and other [[passenger train]]s pulled by freight style [[hood unit]] locomotives, which have external walkways.

==History and development==
The [[EMD SDP45]] performed well in passenger service, but the [[Atchison, Topeka and Santa Fe Railway|Santa Fe Railway]] felt its utilitarian appearance was unsuitable for its passenger trains. [[Electro-Motive Diesel|EMD]] therefore designed a lightweight "cowl" body to cover the locomotive, though it did not, as in earlier [[cab unit]]s, provide any structural strength, which remained in the frame.  The cowl provided sleeker looks, better aerodynamics at speed, and allowed the crew to enter the engine compartment en route for diagnostics and maintenance. Final drive [[gear ratio]] for passenger service was 57:20.<ref>{{cite web |title=Santa Fe F45's |url=http://atsf.railfan.net/cowls/f45.html |website=atsf.railfan.net |access-date=3 August 2021}}</ref>
==Orders==
Santa Fe purchased nine of the locomotives (road numbers 100 through 108), and the [[Milwaukee Road]] bought five for its passenger service (road numbers 1 through 5). The Milwaukee Road units were delivered without dynamic brakes. Reportedly, [[Illinois Central Railroad]] was considering an order for five FP45s as well (EMD order #5742, serial #s 34952–34956), but canceled it. Such low production was feasible and profitable for EMD since the locomotive was fundamentally just a re-clothed [[EMD SDP45|SDP45]].  Power, as in the [[EMD SDP45|SDP45]], was from a [[V20 engine|V20]] [[EMD 645E3|645E3]] engine (or [[Prime mover (locomotive)|prime mover]]) developing {{convert|3600|hp|abbr=on|lk=in|sigfig=3}}.

A freight-only derivative, the [[EMD F45]], was sold in greater numbers (86) to Santa Fe, the [[Great Northern Railway (U.S.)|Great Northern Railway]], and the [[Burlington Northern Railroad]]. Amtrak purchased a similar passenger locomotive based on the {{convert|3000|hp|abbr=on|lk=in|sigfig=3}} [[EMD SD40-2|SD40-2]], the [[EMD SDP40F|SDP40F]]. After a series of derailments and their subsequent withdrawal, Amtrak traded 18 units to the Santa Fe, where they were converted for freight use. The converted locomotives were designated as SDF40-2.

The last three F45s in service were on the [[Montana Rail Link]] and the [[New York, Susquehanna and Western Railway]] in the northern and northeastern United States. These units were taken out of service in 2006 for the MRL and 2010 for the NYSW. Three are known to survive, with one located at the [[Izaak Walton Inn]], now converted into a lodge. {{Citation needed|date=January 2023}}

==Rebuilds==
Between April 1980 and December 1982, [[Atchison, Topeka and Santa Fe Railway|Santa Fe]]'s San Bernardino shops rebuilt eight FP45s 5940–5943, 5945–5948. They emerged as 5990–5993, 5995–5998, and were redesignated SDFP45s. The 5944 was retired in September 1981 on account of a wreck at Toland, Texas. Electrically they were upgraded to [[EMD SD45-2|SD45-2]] standards. Mechanically, they were re-geared from 59:18 to 60:17, reducing their top speed from 89 to 83&nbsp;mph (143 to 134&nbsp;km/h).

In the mid-1980s Santa Fe again re-geared them - this time to 62:15 for 71&nbsp;mph (114&nbsp;km/h).

==Withdrawal==
Milwaukee Road's FP45s were all sold for scrap in 1981 and 1984. Santa Fe SDFP45 No. 5944 was wrecked in 1981, Santa Fe SDFP45 No. 96 was wrecked in 1994 on Cajon Pass. While No. 91 was sold to the [[Wisconsin Central Ltd.|Wisconsin Central]] in January 1995, becoming their #6652 and the rest stayed in service right up until the BNSF merger in September of 1995, and were retired shortly after the merger.

== Preservation ==
Those that were not wrecked in service, or sold to other railroads, are on display in museums:
* '''Santa Fe 90''': was donated to the [[Oklahoma Railway Museum]] in [[Oklahoma City]] in a non-operational state. #90 was the last FP45 donated by the Santa Fe and had resided on a [[RIP track]] for two years before being delivered to the museum.
* '''Santa Fe 92''': was donated to the [[Illinois Railway Museum]] in [[Union, Illinois]]. In 2010, volunteers restored 92's control stand so that it could control other locomotives via MU. The locomotive was moved to National Railway Equipment in Silvis, IL during July 2017, where a replacement 20-645E3 engine, AR10 [[alternator]], and a WBO air compressor (all purchased by the museum) were installed. This made the locomotive fully operational for the first time since at least 1997.
* '''Santa Fe 93''': preserved at the [[Great Plains Transportation Museum]] in [[Wichita, Kansas]]. It was delivered in June 1999 and has undergone cosmetic restoration. Another cosmetic restoration is underway.<ref>{{Cite web |author=KWCH Staff |date=2023-09-25 |title=Actor leading Wichita museum's effort to restore Santa Fe locomotive |url=https://www.kwch.com/2023/09/25/actor-leading-wichita-museums-effort-restore-santa-fe-locomotive/ |access-date=2023-09-26 |website=www.kwch.com |language=en}}</ref><ref>{{Cite web |last=Franz |first=Justin |date=2025-08-22 |title=Santa Fe FP45 to be Restored |url=https://railfan.com/santa-fe-fp45-to-be-restored/ |access-date=2025-08-23 |website=Railfan & Railroad Magazine |language=en-CA}}</ref>
* '''Santa Fe 95''': preserved at the [[Western America Railroad Museum]] in [[Barstow, California]].
* '''Santa Fe 97''': preserved at the [[Museum of the American Railroad]] in [[Frisco, Texas]]. Currently under restoration, will be renumbered back to Santa Fe 107.
* '''Santa Fe 108''': was donated in operating condition minus the cab's air conditioner to the [[Southern California Railway Museum]] at [[Perris, California]].  This locomotive has the distinction of being the last passenger locomotive ever purchased by Santa Fe.  Its restoration was completed in October, 2018 and it is now in operating condition for the first time since 2012.<ref>{{cite web |last1=Busse |first1=Dave |title=Santa Fe 'Warbonnet' FP45 comes alive in California |url=https://www.trains.com/trn/news-reviews/news-wire/08-santa-fe-warbonnet-fp45-comes-alive-in-california/ |website=Trains.com |publisher=Trains Newswire |access-date=12 February 2024 |archive-url=https://web.archive.org/web/20181010231628/http://trn.trains.com/news/news-wire/2018/10/08-santa-fe-warbonnet-fp45-comes-alive-in-california |archive-date=10 October 2018 |location=Perris, CA |date=8 October 2018}}</ref>
