1. Introduction to the Evolution Series
The GE Evolution Series represents a significant advancement in locomotive technology, designed to meet stringent environmental regulations while maintaining powerful performance. This guide, based on Sean Graham-White's authoritative book, provides an overview of these modern locomotives, their innovative design, and their impact on North American railroading.
At the core of the Evolution Series' success is the GEVO 12-cylinder engine, which achieves the same horsepower as older 16-cylinder FDL engines with reduced fuel consumption and lower emissions. These locomotives have been widely adopted by every Class 1 railroad in North America since their introduction.
2. Development and Design Philosophy
The Evolution Series was the result of over six years of development and an investment exceeding $200 million, primarily driven by the need to comply with the Environmental Protection Agency's (EPA) Tier 2 emissions regulations. General Electric incorporated numerous technological innovations, resulting in over 25 U.S. patents.
The design process involved extensive research, manufacturing, and rigorous testing at GE's facilities in Erie, Pennsylvania. The book delves into the intricacies of the GEVO powerplant and the overall locomotive architecture, providing insights into how these machines were engineered for efficiency and environmental responsibility.
