In 1912, the decision was made to procure a modern steam locomotive to supplement the electric vehicles in the Berlin area, whereupon Henschel developed a machine with the designation T 14. Since the test operation showed that the additional effort for the three cylinders was not worth it, the Union Gießerei in Königsberg manufactured a machine with similar dimensions but only two cylinders in the following year, which was finally procured as the T 14 in series.
It was a tank locomotive with the wheel arrangement 2-8-2T, whose coupled wheels had a diameter of 1,350 mm and allowed a speed of 65 km/h. Due to an unfavorable weight distribution, the leading axle was more heavily loaded than the coupled axles with 17.3 tonnes. The third coupled axle, which served as the drive axle, only carried a load of 14.2 tonnes.
The Prussian State Railways procured a total of 457 T 14s between 1914 and 1918, and a few more were bought by the Reichseisenbahnen Alsace-Lorraine and private railways. When it was taken over by the Reichsbahn, there were still exactly 400 examples from Prussia that became the class 930-4. During the Second World War, some engines that had been handed over in 1918 as reparations came back to the Reichsbahn. After the war, the distribution between the two German states was about the same, and so 138 pieces came to the Federal Republic of Germany to the Bundesbahn and 160 to the GDR to the Reichsbahn. While the last ones were retired in the west as early as 1960, some units in the east were even given a computer number with class number 093 until they were retired in 1972.
