I haven't seen anything here about the book that just arrived on my desk, "Building Union Pacific 844" by noted author John E. Bush, so I thought that I would pass this along. This is a 56 page softbound book about the UP FEF-3 class 4-8-4's. The information contained in this book was gleaned from documents of Wilhem A. Fleischer who was UP's representative to ALCO during the construction of the FEF-3 class locomotives. The information was recently found by his grandson Richard Fleischer in a box by pure chance.
While I haven't yet had a chance to read this book, it definitely looks to be one the serious UP fan will want on their bookshelf. You can find it and other RR books at: South Platte Press
