Query: A "must have" for railroad historians!

This book (hardcover), has to weigh a couple of pounds and is ALL maps. It shows the physical plant of Northeast railroading just after World War II. If you are fortunate enough to have a collection of individual railroad-issued maps you will know the routes that these railroads ran, but this book will show you just WHAT was along the routes. Items such as stations, interlocking plants, junctions etc are listed. As a practical aside, if you are reading an issue of a railroad magazine that highlights an area like Maybrook yard in New York, the maps in this book can help you follow the story accurately!. The ONLY thing this book has that keeps it from being a 5-star is that all of the maps are drawn in ink instead of some other reproduction process. For a map affectionado(sic)? like myself this is not a problem, but if someone is wanting a coffee-table picture book with maps, then this book is not for you. For everyone else, HIGHLY recommended!
