The EMD F59PH is a four-axle 3,000 hp (2 MW) B-B diesel-electric locomotive built by General Motors Electro-Motive Division in two variants from 1988 to 2001. The original F59PH was designed in consultation with GO Transit for commuter operation in Toronto. The design was successful and became the backbone of GO Transit's fleet for two decades. Another major operator is Southern California's Metrolink, which launched with F59PHs in 1992. Production of the F59PH ended in 1994, with 73 locomotives built.

The F59PHI was designed for Amtrak California intercity service and began production in 1994. It is distinguished from the F59PH by its streamlined cab. A total of 83 F59PHIs were built between 1994–2001, primarily for commuter operators.

The F59PH was the first in the "F59" series of locomotives. 73 locomotives were built from May 1988 to May 1994 for two commuter transit railroads, Metrolink of Los Angeles, California, United States and GO Transit of Toronto, Ontario, Canada. While Metrolink continues to use these locomotives today, in 2008, GO Transit began discontinuing operations using this locomotive in favour of the new MPI MP40PH-3C. Only eight locomotives that were refurbished in 2011 remain in service. Those eight locomotives will be replaced upon the delivery of the MPI MP54AC locomotives.

This locomotive is equipped with a turbocharged EMD 12-710G3A, a 12-cylinder, two-stroke Diesel engine (prime mover), front and rear platforms, a full-width cab with a three-piece windshield. Earlier EMD cowl-type locomotives had used a two-piece windshield, while the Canadian comfort cab used a four-piece design.
