German railway wagon classes

The system of German railway wagon classes was introduced in Germany in 1902 and 1905 by the Prussian state railways based on their system of norms, and was soon taken up by the other state railways. On the formation of the Deutsche Reichsbahn, the system became mandatory across the whole of Germany. In the course of the years more and more adjustments to it were made. It was finally replaced between 1964 and 1968 when the two German railway administrations - the Deutsche Bundesbahn and the Deutsche Reichsbahn - adopted the internationally standard UIC classifications for passenger coaches and goods wagons. Today, you will still find the system regularly being used for narrow gauge goods wagons, because these were not generally given UIC designations, as well as on many historic vehicles.
The wagon class comprises one or more main class letters and possibly several secondary class letters . Combinations of several main class letters are possible, e.g. on passenger coaches with different accommodation classes.

Main class letters

In order to distinguish bogie wagons, the last letter of the main class was doubled to begin with, e.g. BC → BCC, G → GG. From 1928 the system was changed on passenger coaches. Instead of doubling the letters, the number of axles was indicated where it was greater than two. So an eight-wheeled BC coach was no longer classified as a BCC but as a BC4. That now made it possible to distinguish passenger coaches with three axles or more. For goods wagons, the doubling of letters was retained. Only on Dgw and ZM wagons was the differentiation dropped, whilst the BT, H, Pwg, V and VO wagons had no bogie variants anyway.
