Procurement
The railway procured a total of 1,027 locomotives of this class up to 1904, and they were stabled at almost all locomotive depots (Betriebswerk or Bw), making them the most numerous German express train locomotives. In addition, several hundred units were manufactured with smaller driving wheels - dubbed the P4 class.
Another 40 examples went to the Imperial Railways in Alsace-Lorraine (see Alsace-Lorraine S 3) and six units, with a modified axle base, to the Grand Duchy of Oldenburg State Railways (see Oldenburg S 3).
