The EMD F59PHI is a diesel-electric engine which is commonly used on passenger trains throughout North America.

The first F59PHI was built by General Motors Electro-Motive Division in 1994 and was the first train to meet California’s strict emission standards. The engine has 3,200 horsepower and is equipped with a turbocharged EMD 12-710E3, 12 cylinder, 2 stroke water cooled “Vee” prime mover. A standard F59PHI has a gear ratio of 56:21 which delivers a top speed of 110 mph.

The F59PHI is also equipped with a secondary electrical generator called a Head End Power (HEP) unit. This provides power to the passenger cars which is used for heating, lighting and air conditioning. This HEP is powered by a dedicated second diesel engine, thus removing the electrical power generation from the prime mover.
