Like the 01, the steam locomotive DRG Class 03 belongs to the type 2'C 1 'h2 or h3. They have 2 consecutive, unified in a bogie, independent of the main frame axles, and 1 independent of the main frame barrel axis. The steam type is superheated steam and the machines have 2 or 3 cylinders.

The steam locomotive DRG Class 03 was built between 1930 and 1938 as a light express locomotive. From this series have been built in about 298 copies. Especially in the boiler and cylinder sector, care was taken to reduce the size significantly. Due to the lighter bar frame, a wheelset mass of max. 18t, reached. A significant improvement, by reducing the weight, could be achieved. In 1934, the steam locomotive DRG Class 03 was given a partial fairing for testing purposes. Due to the aerodynamic fairing a performance gain of up to 290 hp could be achieved. The Class 03 was also characterized by its low steam consumption. The cole consumption could be significantly reduced.

Applications of the steam locomotive DRG Class 03

The locomotives were preferably used in northern and eastern Germany, where numerous major railways were not yet developed for 20 tons of axle mass. After the Second World War, 86 steam locomotive DRG Class 03 became DR and 144 Class 03 was taken over by the DB. Furthermore, about 40 machines were sent to the Polish state railway PKP. The DRG Class 03 were located in Osnabrück, Hannover, Mönchengladbach and Trier. From 1968, the use of the steam locomotive Class 03 was largely superfluous. The last DB machines were used in Ulm until 1972 on the main line to Friedrichshafen. Few machines of the series 03 are still visible today or operational. In the railway museum Dresden-Altstadt a copy of the steam locomotive Class 03 can be admired. Another copy is exhibited in the Technikmuseum Speyer. An operational steam locomotive of the series 3 is available in the DB Museum Nuremberg (Halle).
