GE "U25B" Locomotives
The GE U25B was the builder's entry, independently, into the main line diesel locomotive market. Part of General Electric's "Universal" road switcher series the U25B was a simple, no frills locomotive that provided ample pulling power and was generally reliable and easy to maintain (both of which improved as GE became a more adept locomotive builder). The success of the U25B, although still far behind leader Electro-Motive Division, proved to General Electric that it could compete in the market and the company would go on to develop an entire line of Universals. For the American Locomotive Company (Alco), however, the release of the U25B was a major blow that would eventually put the company out of the locomotive market
