Image:GE Genesis Amtrak.jpg Genesis (officially trademarked GENESIS) is a series of locomotives produced by GE Transportation Systems, a subsidiary of General Electric in Erie, Pennsylvania. The engines are largely used for providing motive power for passenger trains in North America. The largest customer for this line of locomotives is Amtrak in the United States, which operates more than 200 of them on its routes. VIA Rail in Canada is also a major customer.

Models

Three major models have been produced, starting in 1992 with the P40DC and continuing into 2005 via the P42DC.

[edit]

P40DC and P42DC

The P40DC (first known as the AMD-103) was the first model, operating in a diesel-electric configuration and using direct current to power the electric motors, developing 4000 horsepower (3000 kW). The P40 was later succeeded in 1997 by the P42DC, which produces 4200 horsepower (3100 kW) and has a higher top speed. Additional deliveries of the P42DC allowed Amtrak to first store, then offer for sale, the majority of the P40DC fleet. [[1]][[2]]

P32AC-DM

A "dual-mode" P32AC-DM locomotive was developed that could either run its electric motors on power from the onboard diesel engine or from a third rail carrying 750 volts of direct current and seamlessly transition between the two modes while underway. The P32AC-DM is unique not only because of third-rail capability, but also because it is equipped with AC (alternating current) traction motors. The P32AC-DM (rated at 3200 horsepower or 2390 kW) is confined to hauling trains entering New York City, where diesel emissions in tunnels approaching Penn Station and Grand Central Terminal are not permitted. Hence it is used on Amtrak's Empire Service, running in electric mode when necessary. The P32AC-DM is mainly used by Metro-North Railroad where it runs in electric mode in the Park Avenue Tunnel.
