In 1882, Henschel delivered the first example of a triple coupled saturated steam locomotive for secondary line service. The T 3 was impressive, it was service-friendly, robust, and versatile. The jurors at the Chicago World's Fair in 1893 were also convinced. They awarded a prize to the 11 year old design. Even 13 years later, the manufacturers still dared to exhibit the T 3. In Milan, Hanomag presented the last locomotive, fitted with a Lentz poppet valve distribution, as an experiment. The exhibition efforts paid off for the companies involved. Same design locomotives went to China, France, Greece, and Italy. The German State Railway gave it the class designation 89.70. In Germany, in addition to the Prussian State Railways, numerous private railroads purchased the T 3. Starting in 1891, the Royal Württemberg State Railways also entered the circle of T-3 operators. The first units were produced by Krauss, in neighboring Bavaria. Thereafter all locomotives came from Württemberg factories, the Maschinenbau-Gesellschaft Heilbronn, and Machinenfabrik Esslingen. The drive gear of the Württemberg locomotives was more powerfully designed, the wheel diameter somewhat smaller. Instead of the Allan valve gear, outside mount, they were fitted with a Heusinger valve gear. They were in service for the German State Railroad as class 89.3. Several units of both classes were employed by the State Railways of both states after 1945. Finally, the 89 7296 and 7377 rolled onto the German Federal Railroad's holding siding in 1961.
