GE Genesis AC4400CW – The First AC-Traction Diesel Engine Locomotive

Img source:

The GE Genesis AC4400CW is the first diesel locomotive with an AC traction system. It was designed for use in North America, Europe, and China.

The ac4400cw engine is a diesel locomotive that was designed by GE. It is the first AC-traction engine to be used on an Amtrak train.

When you think of a locomotive with a single, high-powered AC-traction diesel engine, the AC4400CW-GE Genesis is the locomotive that comes to mind first. This locomotive, designed by none other than General Electric, is one of the most commercially successful AC-traction diesel locomotives in North America. Let’s have a look at this article to discover more about this locomotive from the United States!

The AC4400CW-GE Genesis Has a Long History

This locomotive’s initial model was launched in 1994, and it immediately garnered a popularity. As mentioned in the introduction, it’s a variant of the C44-9W “Dash 9,” a kind of DC-traction diesel locomotive. One of the reasons that has contributed to this locomotive’s appeal is the fact that it features an AC-traction diesel engine.

If a difficulty arises, the engine simply inverts the DC that is supplied to the traction motors, utilizing separate invertor banks for each traction motor. Unlike EMD, the issue may be solved by removing the traction motors one by one. The whole traction motor must be removed from EMD locomotives.

By 1998, manufacturers had developed three-phase AC power that was delivered to the traction motors, making this AC-powered engine very popular. The technology of the IGBT was included into the new AC4400CW-GE Genesis versions so that locomotives may benefit from it. It’s also the first GE model to have a far more sophisticated microprocessor control system, enabling it to stand alone rather than being part of the Dash 9 series.

The AC4400CW’s engine is a GE Genesis.

A diesel engine with a maximum output of 4,400 horsepower powers the AC4400CW-GE Genesis locomotive. GE Transportation System developed it, and it utilizes AC traction motors instead of DC, with a separate converter for each motor.

The AC4400CW-GE Genesis is now inactive.

Although a handful are still in use for revenue services, the most have been decommissioned as a result of numerous accidents. On the other hand, the model ES44AC was created as a successor.

What Engine is in a GE Genesis AC4400CW?

The AC4400CW-GE Genesis locomotive is powered by a 4,400 horsepower diesel-electric engine.

What is the lifespan of an AC4400CW-GE Genesis?

The AC4400CW-GE Genesis locomotive has a length of 22.30 meters.

What is the total number of AC4400CW-GE Genesis?

A total of 2,834 AC4400CW-GE Genesis locomotives have been manufactured by GE. While some are still operational, the majority have been disassembled for destruction.

What is the Horsepower of an AC4400CW-GE Genesis?

The AC4400CW-GE Genesis has a horsepower rating of 4,400.

What is the price of an AC4400CW-GE Genesis?

Although the precise price has yet to be revealed on the internet, it is expected to cost about $2 million, similar to other conventional AC-engine locomotives.

Are there any more AC4400CW-GE Genesis models?

The ES44AC, which was developed to replace this type, is one of the several variants of the AC4400CW-GE Genesis locomotive.


The AC4400CW-GE Genesis locomotive is another illustration of how locomotives have developed through time. As the first AC-traction locomotive, it served as a signal to other locomotive manufacturers that the time had come to concentrate on creating a fuel-efficient but powerful engine for its North American clients.

For as long as he can remember, Peter has been constructing model trains. This site is a creative avenue for him to go further into various sizes and elements of the model train community and hobby. He is an ardent lover of HO and O scale.

The ac4400cw vs dash 9 is a new locomotive that was released by GE. This locomotive is the first AC-traction diesel engine locomotive in North America.
