The GE 25-ton switcher (also known as a 25-tonner) is a model of diesel-electric switcher locomotive that was produced by GE Transportation at their Erie, Pennsylvania, facility between 1941 and 1974. Most examples were produced for industrial customers or the United States Armed Forces, although a number of examples were purchased by freight railroads as well. Production totaled approximately 550 units over 33 years for customers on five continents, making it one of the most widely produced switchers in American history. The small size, low top speed (20 mph or 32 km/h) and low power output (150 hp or 110 kW) of the locomotive made it unsuitable for much beyond switching duties. GE specifically marketed the locomotive as an industrial switcher with a low cost. Many 25-tonners operated for decades, and into the 21st century. A number have been preserved at museums, where some continue to perform switching duties.
