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.[1] 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.[2] Only eight locomotives that were refurbished in 2011 remain in service. Those eight locomotives will be replaced in Fall 2016 when the MPI MP54ACs are delivered.

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.[2]

The F59PH is still used today, mainly on commuter railroads. Metrolink has rebuilt most of their F59's with a bigger radiator and E-bell, giving them a designation "F59PHR".

The EMD F59PHI is a common diesel-electric locomotive on passenger trains in North America, built originally by General Motors Electro-Motive Division (EMD), now built by the successor company, Electro-Motive Diesel, which is owned by Progress Rail Services, itself a division of Caterpillar.

First built in 1994, the locomotive is a 3,200 hp (2.4 MW) B-B diesel-electric locomotive intended for service on North American mainlines.[3] This locomotive is equipped with a turbocharged EMD 12-710G3C-EC, a 12-cylinder, 2 stroke diesel engine (prime mover). The main (traction) alternator converts mechanical energy from the prime mover into electrical energy that is distributed through a high voltage cabinet to direct current traction motors. Each of the four traction motors is directly geared to a pair of driving wheels. The gear ratio of the traction motors (model D87BTR) to wheel axle determines the maximum operating speed of the locomotive; a standard F59PHI has a gear ratio of 56:21 which provides a top speed of 110 miles per hour (180 km/h).

The F59PHI has a fully enclosed carbody which provides protected walkways for easy access to the engine room and trailing units. This arrangement allows routine maintenance while the locomotive is in service. The noteworthy aspect of this locomotive's exterior is the use of composites to present a streamlined appearance.[3]

To supply electrical power for passenger service, the F59PHI is equipped with a secondary electrical generator referred to as the Head End Power (HEP) unit. The head-end generator generates AC power at 480 V, 60 Hz AC, and can be rated between 500 and 750 kW (670 and 1,010 hp) to provide power to the passenger carriages for lighting, electric heating, and air conditioning. The head-end generator is powered by a second diesel engine dedicated to it. With this arrangement, the prime mover is not burdened by head-end power generation and consequently is used solely for supplying tractive effort.

When it debuted for Caltrans in late 1994, the F59PHI was the first locomotive in the United States which met California's stringent emission standards.[3]

Examples of the F59PHI are currently operated by these companies:

Accidents and incidents[edit]

On February 24, 2015, Metrolink locomotive #870 was pushing (the locomotive was located at the rear) a passenger train that struck a vehicle obstructing the line at Oxnard, California and was derailed. One person was killed and 29 were injured.
