The ** EMD F59PH** is a four-axle 3000 hp B-B diesel-electric locomotive built by General Motors Electro-Motive Division from 1988 to 1994. A variant, the F59PHI, was produced from 1994 to 2001. The F59PH was originally built for GO Transit commuter operation in the Toronto region. Metrolink in Southern California also purchased a fleet for its 1992 launch. The streamlined F59PHI was designed for Amtrak California intercity service. A total of 72 F59PH and 83 F59PHI locomotives were built.

F59PH

Between May 1988 and May 1994, 72 F59PH locomotives were built for two commuter transit railroads: GO Transit of Toronto and Metrolink of Los Angeles. Based on the GP59, the locomotives had a turbocharged EMD 12-710G3A, a 12-cylinder, two-stroke diesel engine (prime mover). Head end power was supplied by a separate diesel generator.{{cite book | url=https://ww2.arb.ca.gov/sites/default/files/classic/research/apr/past/a032-169&92-917a.pdf |title=Controlling Locomotive Emissions in California: Technology, Cost-Effectiveness, and Regulatory Strategy |date=March 1995 |publisher=California Air Resources Board |first1=Christopher S. |last1=Weaver |first2=Douglas B. |last2=McGregor |page=27}}

GO Transit began retiring its F59PH locomotives in 2008 in favor of newer MPI MPXpress locomotives. Most were purchased by other operators including Exo (10 locomotives), Metra (3), NCDOT (11) for use on the Piedmont, and Trinity Railway Express (7).

Seven Metrolink units were rebuilt as F59PHR. The non-rebuilt Metrolink locomotives were retired by 2020. Five of those were purchased by NCDOT in 2018.

F59PHI

The F59PHI is a variant with a fully enclosed streamlined carbody. The first nine units were purchased by Caltrans for use on Amtrak California services and entered service in 1994. Like the F59PH, the F59PHI is equipped with a secondary electrical generator – rated between 500 and – for HEP. A total of 83 locomotives were built, most for commuter rail and Amtrak corridor services on the West Coast.

Two F59PHI locomotives were built in 1995 for Philip Morris Companies to haul the Marlboro Unlimited, a custom built luxury train to carry winners of a Philip Morris sweepstakes around the country. After Philip Morris cancelled the train, the units were stored before being sold to Metrolink in 1998.

Some units are still in service with the original owners, while others have been retired. The 21 ex-Amtrak units were sold to Metra in 2018.

Preservation

In January 2026, Metrolink has donated their first F59PH, numbered #851, to the Fullerton Train Museum in Fullerton, California, making it the museum's first locomotive and the first locomotive Metrolink donated for preservation. #851 was rebuilt into an F59PHR in 2010 and retired in 2024.
