Also the Deutsche Reichsbahn (DR) in the Soviet occupation zone was forced to manage only shortage in all areas. Quick new procurements and repairs were not possible at the DR. In order to facilitate maintenance work, a class shake-out was made with the attempt to home-base each car type only at a few Reichsbahn directorates and stations. Of course this measure yielded only a partial success and was never implemented properly. Also, many details on the coaches were simplified for easier maintenance. The roof windows were omitted and completely closed. Half of the doors on each coach side were omitted which hampered the passenger exchange but saved material. Consequently, a new floor plan with passageway was worked out and new interior equipment installed. Starting in 1963, new coaches were built in analogy to the DB by combining a refurbished underframe with a new vehicle body. The DR called that "Rekowagen" - according to the "Reko locomotives" already available in stock (Reko - for reconstruction). In 1970, the last compartment coaches were still in service, but did not receive an EDP-compatible number anymore.
