Kalamazoo railroad motor cars were good sellers overseas, particularly in South America and Australia. In fact, the generic term for railroad motor car in Australia was "Kalamazoo". In contrast, the company was never were more than a minor player within the United States, most railroads having just a few of the cars around. Perhaps the company's best-known war-time product was "Galloping Gertie", a railroad motor car with a large target above it used for gunnery practice. Larger railroad motor cars were the models 27A (10 men capacity), 27AW-F (10 men capacity), and 38B-F (14 men capacity). Adding side steps could double the number of men carried. The 27A had an air-cooled four-cylinder Wisconsin engine with magneto ignition and a Zenith carburetor that developed 22 horesepower. The 27AW-F and 38B-F had a water-cooled four-cylinder Ford engine that developed 40 hp. Other products in 1960 that ran on the rails included a power tamping jack, a ballast equalizer with plow and sweeper, a spike driver and a line of trailers and push carts. Track gauges and levels, plus portable setoff assembly and take off rails rounded out the catalog. In 1968, the railroad business of the company was bought out by Tamper Inc. of Columbia, South Carolina, and all future railroad equipment was built in South Carolina under the Tamper brand. Tamper merged with Fairmont in the 1990s, which was then bought by Harsco Corporation. Meanwhile, the company continued to build Speed Truck products. The model K45 was the largest platform truck in their 1960s catalogs with a 3,000-pound payload. The model 2500 platform truck could carry 2,000 pounds, as could the Model E1900 Low Bed Electric. The Kal-Truk was a three-wheel carrier most often used as a dump truck. It could carry 3,000 pounds. Finally, there was a small Electric Runabout, the "Economizer," which was a personnel carrier only. The company manufactured four passenger vehicles for use at the 1964-65 New York World's Fair. This custom model was called an "Escorter" and a total of 150 were made. In 1966, the Hawk family of Kalamazoo, who had owned a controlling interest in the company since 1953, bought out the remaining shares. Despite a number of strikes by the union workforce, the Kalamazoo Manufacturing Company continued building its personnel and materials carriers, reaching the company centennial in 1983.
