Query: Terrific Book!

A West Coast railfan, I learned only recently that there are trains east of the Mississippi. I discovnered this when my friend Lee told me that his dad had been president of the New York Central System (and also the D&RGW and Western Pacific). This book details the greed and corporate shenanigans of the modern day robber barons and their mega-merger giants - Penn Central, Conrail, Amtrak, CSX, NS. And the efforts of a few principled railroad leaders to save their dying industry. It's a history so fascinating that it reads like a novel. I'm waiting for the movie to come out!
