"Electro-Motive E-units and F-units" by B. Solomon-Opinions?

Would anyone who has had an opportunity to read Mr. Solomon's new title on the E's and F's be kind enough to share his/her thoughts regarding it? The subject matter of the book is of great interest to me but I'd like to hear what others think before ordering a copy.

Thanks in advance for any replies.

I have not read it, but Brian is a good writer. His information is accurate becaise he interviews railroaders who have experience in that area. I have helped on his projects, along with several other mutual railroader friends. I'd buy it.
