Electro-Motive Diesel, Inc. (formerly the Electro-Motive Division of General Motors Corporation) is currently the worl'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.
