  4rail.net - Rolling Stock - GE ES44AC, ES44DC and ES44C4       

The Evolution Series from General Electric Transportation is a product of 60 years of serious product development. The GE ES44AC, ES44C4 and ES44DC / ES40DC locomotives offer their customers a consept rarely seen before. In addition to its powerful advanced features, the manufacturer General Electric offers these locomotives full upkeep with on-the-road-diagnostics. The availability of the locomotives is better than normally because once the diagnostics shows that a part starts to show need of maintenance, the locomotive notifies its need for attention and the necessary parts can be sent to the point of need without delay. This way GEs customers can make more business than most other locomotive builders customers, and this care translates to more income.  

Picture: The Heritage 3 painted BNSF ES44DC is the lead unit of a string of 4 General Electric locomotives on the point of a 500 axle train waiting to cross over the mountains via Tehachapi pass in California U.S.A. BNSF Railway is currently ordering 3/4s of its locomotives from the General Electric, a living proof of working relationship between the manufacturer and the customer! Picture by John McKey 2008.

     

While the manufacturers product consept is state of the art, the products themselves can take continuous use with their built rugged design. The AC models provide more power to the rail when operating at higher speeds, like BNSF hot shot stack and trailer trains, while the DC models can start as large trains which require less speed to reach their destination. The newest to the family, the ES44C4 has so far been delivered to the traditional lead customer BNSF where they work the fast stack trains. The C4-version has 6 axles like the other two, but only 4 are motored. It remains to be seen if this concept will prove effective with the high horse power locomotives. It might well be that the C4 version is priced the same as the DC version, and the customer in this market always want the 'better' AC version. The AC versions earlier cost twice the price of a DC versions! From the GEs viewpoint manufacturing just one type of components clearly makes sense. And the customer may rigtly consider that upgrading the locomotives to full ES44ACs is easy later by adding the missing 2 motors plus what is needed to power them. A concept that has benefits for both sides. However, it remains to be seen, if the starting traction of the ES44C4 will match enough that of the DC version in the difficult conditions where the train nearly stalls.
