The Prussian T 16.1 locomotives were built for the Prussian state railways as goods train tank locomotives about the time of the First World War. Six examples were also procured by the Imperial Railways in Alsace-Lorraine.
Including follow-on orders by the Deutsche Reichsbahn, a total of 1,242 locomotives were delivered between 1913 and 1924. They were later redesignated as DRG Class 94.5–17 by the DRG in their renumbering plan and were given the numbers 94 502–1380 and 94 1501–1740. Three of the T 16.1 engines belonging to the Imperial Railways in Alsace-Lorraine remained in Germany and were given numbers 94 1378–1380. In 1935, locomotive numbers 94 1381–1384 from the Saar Railway went into the Deutsche Reichsbahn. As part of the reparations required of Germany after the First World War, quite a few examples were given to the Polish State Railway, where they were designated the TKw 2. Some of these locomotives were given the Reichsbahn numbers 94 1385–1416 in the Second World War. After 1945 several former French and Belgian locomotives were left with the Deutsche Reichsbahn in East Germany as numbers 94 1801–1810. In addition, in 1950, another T 16.1 from the Halberstadt-Blankenburg Railway was acquired and numbered as 94 6776. On the introduction of the new DB renumbering scheme in 1968 the Deutsche Bundesbahn locomotives were redesignated as Class 094; the DR renumbering scheme of 1970 saw the DR in East Germany reclassifying its engines as Class 94.1.
