Electro-Motive Diesel, Inc. (formerly General Motors Electro-Motive Division) is currently the world's second largest builder of
railroad locomotives in terms of overall sales.
General Electric is the largest, overtaking EMD in the mid-1980s, and between them they have built the overwhelming majority of the locomotives in service in
North America and a large proportion of those in the rest of the world as well. EMD is the only diesel-electric locomotive manufacturer to have produced more than 70,000 engines and has the largest installed base of diesel-electric locomotives in both North America and internationally. Additionally, EMD can lay claim to being the company that ended the dominion of the
steam locomotive on the world's railroads, by both producing high-quality, reliable locomotives, and just as importantly (maybe more so) knowing how to sell them.
