A total of 68 examples of this locomotive were produced by various manufacturers between 1884 and 1906. Of these, 51 (the so-called T 3a) corresponded to the older version of the Prussian T 3 with a regulator on top. The other 17 (the T 3b) conformed to the more powerful version with a steam dome. Two of the latter locomotives were given a Walschaerts valve gear instead of the usual Allan valve gear. They were employed primarily on branch line and shunting duties. The last locomotive was retired by the Deutsche Reichsbahn in East Germany in 1963.
