This article contains a list of locomotives and railbuses of the Deutsche Reichsbahn (East Germany) (DR) according to the numbering system introduced by the DR on 1 July 1970. Following the October 1990 reunification of Germany, the DR's locomotives and railbuses were incorporated (and renumbered) on 1 January 1992 into the classification system of the West German Deutsche Bundesbahn (DB), originally issued on 1 January 1968, in preparation for the merger of the two German national railways that took place on 1 January 1994. This renumbering was also described as the 'locomotive classification of the Deutsche Bahn' as a number of changes and additions to the DB's 1968 system were needed.
