1970
Although the five-part double-decker articulated trains, double-decker articulated trains, type 1970 and type 1957 had proven their worth in use, they nevertheless had some weak points. The most serious was the exceeding of the axle load of 20t of the middle bogies with more than 150% occupancy. In order to remedy this disadvantage, the successor trains acquired from 1970 were shortened by 1 compartment each, even if this reduced the number of seats per train by 80. Since only 1 flight of stairs led to the lower floor, space for sufficient battery capacity could be created in the space gained, so that the train no longer had to be supplied with electrical energy by an additional diesel generator when it was idle for a long time. As these trains, in contrast to their predecessors, were designed primarily for local traffic in metropolitan areas, 25 trains were given a control compartment at one end of the train, and a further 6 were delivered without a control compartment. The first trains were stationed in Leipzig and Halle. Some of the trains in Halle were delivered ex works for the S-Bahn under construction in red. Such trains also ran on the Elbe valley line of the Dresden S-Bahn, in the Berlin area and for commuter traffic from Greifswald to the "Bruno Leuschner" nuclear power plant in Lubmin. The use in Greifswald was remarkable as three-part train units of class 110 diesel locomotives in the composition DBGqe - 110 - DGB (q) e - 110 - DGBqe were driven (1680 seats / train !!). Some trains were also used in long-distance traffic during the season, whereby normal dining cars could be provided to supply passengers.
The new articulated trains also ran on branch lines in the vicinity of larger cities (e.g. Erfurt - Langensalza, Fröttstedt - Friedrichroda). They could also be seen on the weekend tourist trains from Leipzig or Halle to Katzhütte in the Thuringian Forest. When the industrial centers disappeared after the fall of the Wall, the star of these previously indispensable trains also fell, and DBAG probably no longer took over any more.
