The class 23 steam locomotives are of the type 1'C 1 'h2. They have 1 mainframe independent axle, three mainframe independent, coupled, trailing axles that run in a bogie, and 1 main axle mounted on the axle. The steam is hot steam and the locomotives have 2 cylinders.
The locomotives acquired by Deutsche Bahn under the designation Class 23 belong to the largest steam locomotive series of the DB. However, with the steam locomotives of the same designation, which had been produced on behalf of the Deutsche Reichsbahn before the Second World War, there was no other connection except in the wheel alignment. The first series (23 001 – 015) was built between 1950 and 1951. The locomotives of this series were used by DB until the end of 1975. The last locomotive of the DRG Class 23 with the serial number 23 105 is located in the city of Heilbronn South German Railway Museum.The manufacture of the steam locomotive DRG were in Kassel based Henschel-Werke GmbH, Krupp Essen and the A. Jung locomotive factory in Jungenthal Kirchen / Sieg and the Maschinenfabrik Eßlingen involved.

Where was the DRG Class 23 used and what special features were there?
The DRG Class 23 locomotives were each designed as a “steam locomotive for heavy passenger train service”. In the construction of belonging to this series locomotives showed new ways open-minded. Over time, details were changed again and again. From version 23 053 onwards, for example, they had a fully enclosed driver’s cab, steam blowers for cleaning the heating surfaces and central lubrication for hard-to-reach drive parts. Over the years, it had also come over again to rebuild the boiler equipment. Up to version number 23 025, each Series 23 steam locomotive was delivered ex works with a tender that had no tapped treads for the water box. Sometimes there were not even stages for the coal box, which was usually produced with two, in some cases with three stages. The empty weight of the steam locomotive DRG Class 23 was 74.6 tons. It was able to carry a maximum water supply of 31m³ and a stock of coal up to a total weight of 8t. With an indicated output of 1785PS, the DRG Class 23 steam locomotive brought it to a traction of 14,600kp and a top speed of 110km / h (forwards) and 85km / h backwards respectively.
