The GE PowerHaul is a class of mainline diesel-electric locomotives designed by General Electric. Thirty locomotives were ordered by Freightliner UK in 2007; the first locomotive was completed in July 2009 at GE's Erie, Pennsylvania plant.

The Turkish state owned rolling stock manufacturer TÜLOMSAŞ has a manufacturing agreement with GE to produce PowerHaul locomotives for European, African and Middle-Eastern markets. The TÜLOMSAŞ plant produced its first PowerHaul locomotive in February 2011. In November 2011 Australian engineering firm UGL Rail announced it was to develop a narrow gauge version of the class in association with GE.

Three main subclasses exist: PH37ACmi for UK railways, PH37ACi a version for mainland Europe and elsewhere built to UIC 505-1 vehicle gauge, and PH37ACmai a version for 3 ft 6 in (1,067 mm) gauge lines.

Versions of the locomotive include the Class 70 used by Freightliner (UK), the DE36000 of the Turkish State Railways, and the Korail Class 7600 (South Korea).

The PowerHaul Class are a 6 axle Co'Co design for heavy mainline freight operations - the design originated in a collaboration between Freightliner UK who required a more powerful freight locomotive, and General Electric who needed a launch customer for its entry into the European rolling stock market. The locomotives are the first GE locomotives manufactured for the European market since the 'Blue Tiger' locomotive built in collaboration with AdTranz.

To fit within European and UK mass and loading gauge restrictions GE used a relatively high revving engine (1500rpm), giving a 20% increase in power-weight ratio. The engine uses the same design of transmission system as used in GE's North American AC drive locomotives: an AC alternator, with AC output rectified to an intermediate DC line, with separate inverters and inverter control for each traction motor, auxiliary power is also supplied by the DC link, using electronic inverter based load control. The PM37ACmi design uses a General Electric GTA series alternator, and 5GEB30 axle hung traction motors.
