During the mid-1800s, American railroads became the lifeblood of new communities in the West and brought new ways of life and means of commerce to rural communities. Railroads became the shining thread that tied together the tapestry of American life into a land of plenty. The Illustrated Dictionary of North American Locomotives explores the story of railroads and their motive power. Giant beasts of iron and steel once roamed the land. Their descendants still race across the country.

This book charts the progress of motive power on America's railroads from 1830 until the present. Its 432 pages illustrate a wide variety of grand and humble locomotives from the steam powered Puffing Billy types of the "Early Days" chapter, to the mighty Allegheny class steamers that were used to haul coal for the American industry in the "Steam in Charge" chapter. Technical specifications are given for each engine type and the book is fully illustrated with both black & white and color photos. The book goes on to show the progress of Diesel Power, including the output of General Electric and General Motors electromotive division (EMD) from the 1920s to the present. Ultimately, the book also explores the Electric Power that powers so many of today's railways.
