The cars were manufactured by RAW Halberstadt in the GDR between 1978-1982. The cars were mainly used in the domestic high-speed rail system as Städteexpress. The first overhaul of the series was started by the Deutsche Bundesbahn at the RAW Delitzsch plant, but later the overhaul was also carried out at the Werk Potsdam plant. After the renovation, they operated as RegioExpress in the territory of the former FRG.
PF Lights can be added to the model, connected with an extension cable to a 9V battery box.
