The EMD F59PH is a four-axle 3,000hp (2MW)B-Bdiesel-electriclocomotive 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.
The F59PHI is a variant with a fully enclosed streamlined carbody.[6] Like the F59PH, the F59PHI is equipped with a secondary electrical generator – rated between 500 and 750kW (670 and 1,010hp) – for HEP.[7]
Seven Metrolink units were rebuilt as F59PHR. The non-rebuilt Metrolink locomotives were retired by 2020.[16] Five of those were purchased by NCDOT in 2018.[17] Metrolink donated F59PHR No. 851 to the Fullerton Train Museum in January 2026.[18]
The first nine F59PHI units were purchased by Caltrans for use on Amtrak California services and entered service in 1994.[6] A total of 83 locomotives were built, most for commuter rail and Amtrak corridor services on the West Coast.[19] 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.[20][21] 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.[22]
