Book excerpt: War is a brutal thing. Countries clash in a grand struggle for power, while belligerent nations mobilize their vast resources to tackle their opponents head-on. Both man and machine, and the supplies to support them, must be moved in mass quantity to have any hope of victory.World War I, or "The Great War" (as it was called at the time), was the first worldwide conflict of its kind, requiring mass mobilizations at unrivaled levels. The rail systems of nations across the globe were put to the test by the war effort. Tasked to move troops, equipment, ammunition, and supplies around the clock, railroads were pushed to the precipice of failure."The Great Railroad War," by Dr. Rudolph Daniels, delves into the often unrecognized and underappreciated history of United States rail operations during and immediately following World War I. Daniels' expertly-written academic history sheds light on the profound impact that American railroads and railroaders had on the war effort. The book covers the unpreparedness of the railroads for an unprecedented war, the 1918 government takeover to ensure operating efficiency, and the relinquishment of the railroads and groundbreaking Transportation Act of 1920.Covering more than just the history, Daniels discusses the operational details of United States rail shipments both at home and abroad, and how these operations interplayed and overlapped with military operations in France and Russia.
