GE Genesis

General Electric Genesis (officially trademarked GENESIS) is a series of passenger locomotives produced by GE Transportation Systems, a subsidiary of General Electric. Between 1992 and 2001, 321 units were built for Amtrak, Metro-North, and Via Rail.

The Genesis series of locomotives was designed by General Electric in response to a specification published by Amtrak and ultimately selected over a competing design presented by GM EMD. The Genesis series are unique among current North American diesel-electric locomotives because of their low height. This height restriction allowed the locomotive to travel easily through low-profile tunnels in the Northeast Corridor. The Genesis series is lower than even the previous-generation F40PH by 14 inches (356 mm), and is the only Amtrak diesel locomotive that meets the clearance or loading gauge requirements on every Amtrak route. A majority of Amtrak's trains are powered by at least one Genesis unit.

Technical design

The Genesis series is unique among recently manufactured North American passenger locomotives in that it uses a single, monocoque carbody design, thus making it lighter, more aerodynamic, and more fuel efficient than its predecessors (F40PH, F59PH, P30CH, P32-BWH). However, this makes it more costly and time-consuming to maintain and repair. Amtrak is installing bolt-on nose cones on its units for easy replacement in the event of a grade crossing collision with a vehicle. As an example of the improvements over the predecessor locomotives, the Genesis is 22% more fuel-efficient than the F40PH while producing 25% more horsepower. In addition, all Genesis locomotives have four-stroke engines instead of the two-stroke engines previously used in EMD counterparts.

GE AC4400CW

The GE AC4400CW is a 4,400 horsepower (3,300 kW) diesel-electric locomotive that was built by GE Transportation Systems between 1993 and 2004. It is similar to the Dash 9-44CW, but features AC traction motors instead of DC, with a separate inverter per motor. 2,598 examples of this locomotive were produced for North American railroads. As a result of more stringent emissions requirements that came into effect in the United States on January 1, 2005, the AC4400CW has been replaced by the GE ES44AC.

As of 2005, every Class I railroad with the exceptions of Norfolk Southern and Canadian National owns at least one AC4400CW. These units quickly gained a reputation as powerful freight haulers, especially in heavy-haul applications.

The AC4400CW was the first GE locomotive to offer an optional self-steering truck design, intended to increase adhesion and reduce wear on the railhead. This option was specified by Canadian Pacific, Cartier Railway, CSX, Ferromex, Ferrosur, and KCS.
