For over a Hundred and Fifty Years the heartbeat of The United States has traveled upon two sets of parallel guideways. First made of wooden stringers laid apart with iron straps, then solid Iron and finally the Steel rails we use today. During that time various means of propulsion have been used, from horses and mules, to the power of water boiled and expanded 1700 times it's size... to the power of the Diesel Engine and the invisible power of the Electric motor. Each type of power had advantages and disadvantages over the other, yet all had wheels 4 feet, 8 and one half inches apart. This book highlights some of the locomotives and rolling stock to include cabooses as well as freight Cars. From a time when nearly 20 percent of the American worker drew their paychecks from the Railroad Industry. Come along and see some of the great machines that once rolled upon the steel rails of yesterday and today, see them in their paint schemes, come ride along in the Locomotive Cabs, in the Cabooses and learn but a small part of the history of the Trains and People who MADE THE THUNDER ON THE HIGH IRON
