In February 2005, General Motors announced its decision to sell its Electro-Motive Division (EMD), thus ending its 75-year association with one of the most renowned brands in railroading. Looking at the heritage of the venerable EMD in light of this momentous development, this monumental volume offers an overview of the great locomotive maker unprecedented in its scope and unparalleled in the spectacular quality of its photographs. Leading railroad author and photographer Brian Solomon provides an authoritative, comprehensive account of EMD's history, from its genesis in 1922 as the independent Electro-Motive Corporation, to GM's acquisition of the company in 1930, and on through the age of today's superpower locomotives. From the earliest 1920s railcars to the iconic mid-century F units, workhorse GP and SD locomotives, and Dash series; to the company's race with its chief competitor, General Electric, to reach 6,000 horsepower, EMD's complete story unfolds here in depth and detail, illustrated with a wealth of archival photos from across the country, as well as a remarkable collection of color photography from top railway photographers of the last half century.
