Deutsche Reichsbahn (East Germany)

Company History: From 1949, the new governments assumed authority for railway operations. The DRG's (or DR's) successors were named Deutsche Bundesbahn (DB, German Federal Railways) in West Germany, and Deutsche Reichsbahn (DR, German State Railways) in East Germany kept the old name to hold tracking rights in western Berlin.

Unlike the DRG, which was a corporation, both the DB and the DR were federal state institutions, directly controlled by their respective transportation ministries. Railway service between East and West was restricted; there were around five well-controlled and secure checkpoints between West and East Germany, and about the same number between East Germany and West Berlin. Four transit routes existed between West Germany and West Berlin; citizens of West Berlin and West Germany were able to use these without too much harassment by the East German authorities.

The DB started in 1968 with changing the locomotive and passenger car serial numbers to the UIC norm. In 1970 the DR followed. The DB started experimenting with the Intercity trains in a new livery (bright orange).

Headquartered in Berlin, it is a private joint-stock company (AG), with the Federal Republic of Germany being its single shareholder. Deutsche Bahn describes itself as the second-largest transport company in the world, after the German postal and logistics company Deutsche Post / DHL, and is the largest railway operator and infrastructure owner in Europe. It carries about two billion passengers each year.

Deutsche Bahn (literally "German Railway" in German) came into existence in 1994 as the successor to the former state railways of Germany, the Deutsche Bundesbahn ("German Federal Railway") of West Germany and the Deutsche Reichsbahn ("German Empire Railway") of East Germany. It also gained ownership of former railway assets in West Berlin held by the Verwaltung des ehemaligen Reichsbahnvermögens (Administration of the Former Reichsbahn Assets).
