BOOK REVIEW: Diesel-Electric Locomotives – How They Work, Use Energy, and Can Become More Efficient and Environmentally Sustainable
While the documentation of diesel locomotives is extensive, Walter Simpson’s new book brings a fresh perspective to the literature. The book is an excellent primer on diesel locomotives that is well-illustrated with photographs and color-coded drawings of diesels and their parts. However, the underlying theme of the book is locomotive energy efficiency, fuel economy and the Environmental Protection Agency’s emissions standards, leading to Tier 4 compliance. There is also a chapter on the environmental sustainability of railroads.
