DRG renumbering plan for steam locomotives
The German Reichsbahn began in 1920 to develop a renumbering plan for uniform designation of acquired by the state railways steam locomotives. This was based on a corresponding series scheme.
- 9.1 1000 mm gauge
- 9.2 900 mm gauge
- 9.3 785 mm gauge
- 9.4 750 mm gauge
History of Umzeichnungsplans
With the founding of the Reich Railways on April 1, 1920, each of the seven regional railways had in Germany ( Prussia, Bavaria, Saxony, Württemberg, Baden, Mecklenburg and Oldenburg - the state railway of Alsace-Lorraine existed only until the end of World War I ) in Germany own rules for labeling of their locomotives. Even in the individual railway administrations, there were differences in the numbering. Not always the mark from the start was designed to change, and so there were also differences.
In the merger of seven regional railways to a common state railway standardizing the labeling was urgently necessary to become a centralized management of the portfolio, which consisted in 1920 of about 400 genera and over 20,000 locomotives to enable. There was including both vehicles that existed only as individual pieces as well as vehicles with several thousand units had been built.
For the final solution of this problem were needed over 5 years and developed under the direction of Gustav Hammer, President of the Reichsbahn Central Bureau of three different plans. The actual renumbering took years so that not all locomotives her new number yet received, because they were retired in the meantime.
The first preliminary reclassification plan
The first renumbering from 1922 still saw other class numbers before the later plans. The steam engines, for example, should be divided according to their intended use and their Wheel arrangement in 99 series. This design has not been developed to the end, as you anticipated problems in the practical implementation. In addition, the plan had too few opportunities to incorporate future technological changes and newly developed and built vehicles.
The second preliminary reclassification plan
The second preliminary reclassification plan from July 25, 1923 corresponded in its basic construction, already the final renumbering plan of 1925. Room for the planned new standard locomotives This had been created. The 99 existing numbers for the steam locomotives were ordered by the following aspects:
- 01-19: express train locomotives
- 20-39: Passenger locomotives
- 40-59: freight locomotives
- 60-79: passenger tank locomotives
- 80-96: freight tank locomotive
- 97: cog railway locomotives
- 98: ( standard gauge ) local railway locomotives
- 99: Narrow gauge locomotives
The third final renumbering
The third, final renumbering of 1925 differed from the previous in essence is that all previously scrapped locomotives - and therefore all the series - have been edited; also some bugs have been fixed in the assignment.
The 1923 newly built locomotives were delivered with the exception of the Bavarian designs already with the new operating point. The actual re-drawing of older locomotives did not begin until 1926.
Locomotives that were classified were then considered as outdated and should be scrapped soon, given serial numbers from 7001 after the series number.
Express train locomotives
The class numbers 01-11 were reserved for 1920 to be developed or under development series of steam locomotives; Locomotives from the collection of regional railways that were to redraw, got the class numbers 12 to 19
