While in West Berlin newer and newer vehicles were built and used, in East Berlin the pre-war A-I and A-II trains were still running. Only the Line E (currently U5) had trains converted from the former Berlin S-Bahn vehicles. The problem with the procurement of the vehicles is that they need a modified design for the smaller profile vehicle, as it has to differentiate the normal shoes, that is why transport companies were reluctant to commission them. In 1974, the LEW "Hans Beimler" had commissioned four prototypes of the new G double multiple unit, called Gustav in popular parlance.

As before, the seats were located alongside the train walls. The top speed was 70 km/h. The smallest unit of these trains were half trains made up of two double multiple units. After intensive testing the LEW Hennigsdorf factory began manufacturing the trains. The production models had lower side windows and a changed front, but were technically the same. 114 cars were built until 1982. There were 24 more, but those were delivered to Greece for a railway line there. They were returned to Berlin in 1984/85.

In 1987 a new batch of GI-trains was delivered, but with technical changes that made coupling them with the older cars impossible. Because of these changes the new trains were called GI/1. Their popular nickname was Gisela. A speciality of these cars was the fact that they had only two doors per side, unlike the other Kleinprofil trains, which had three. Before the fall of the Berlin Wall, the last trains were delivered on October 1989. It replaced all the BVG Class A trains by 5 November 1989.

Most of the trains were deployed to the former eastern part of U2, before reusing it on U1 (Schlesches Tor - Ruhleben) for the increasing night service in December 1990, before deploying it on U12 and U15 after the U2 was reconnected in 1993. As of today, this trains are deployed on U1 and U2. Those trains are not deployed on U3 and U4 unless it is for emergency use. Trains were renumbered to use 2xx - 4xx numbers in 1992.

All the older G stock were sold to Pyongyang (GI), the G cars went for scrap in 1997, and all the GI/1 trains were refurbished into GI/1E from 2005 to 2007 in order to extend its lifespan.
