Comprehensive History of Amtrak

Three authors who do not claim experience concerning passenger railroading in the United States, or advocacy for same, have joined forces to present a 220-page history of Amtrak; from the situation before it began, through its origin and early days, to a glimpse of “America’s Railroad” today. Their work is comprehensive, scholarly and loaded with politics, as could be expected.
