I guess I haven't given this much thought.....

… but how do GEVOS get their name & I take it it’s related to GE units ?

GEVO is derived from “GE Evolution” (I think) and it refects the prime mover under the hood.

  • Detailed Information

    The name says it all

    GE’s EvolutionTM Series locomotives prove that it is possible to reduce locomotive lifecycle costs while simultaneously meeting the more stringent Tier II emissions requirements from the U.S. Environmental Protection Agency.

    This five-year, US$ 250 million ecomagination project has resulted in a locomotive that improves fuel efficiency while reducing emissions. As the name implies, EvolutionTM Series locomotives incorporate the best of existing, proven diesel locomotive engineering with our newest, most advanced technologies.

    A closer look at an EvolutionTM Series locomotive’s advanced engine technology, control system and cooling system prove that saving money and the environment are not mutually exclusive.

    More information about the EvolutionTM Series locomotive

    The new GEVO 12-cylinder diesel engine in the EvolutionTM Series locomotive produces the same 4,400 horsepower as its 16-cylinder predecessor. And it does so using less fuel.

    The GEVO-12 engine produces 40 percent fewer emissions than our prior models.

    The EvolutionTM Series locomotive incorporates our most advanced cooling system in rail transport to increase reliability while lowering maintenance costs.

    In addition to a standard radiator and fan configuration, locomotives powered by the GEVO-12 engine use dual fans to enhance performance while lowering emissions.

    The consolidated control architecture also makes it easier for customers to upgrade software to enhance performance and achieve lower emissions.

    Compared to locomotives manufactured 20 years ago, GE’s EvolutionTM Series locomotive produces 83 percent fewer particulates and 60 percent fewer nitro

Thanks for the info ! I kinda figured that somewhat, but since I model the early '90s, I guess you can say I have my head stuck up those gas guzzlin GP30s tailpipes …lol.
