The Class G is an electric multiple unit train type used on the Berlin U-Bahn. The trains were originally developed for the Berliner Verkehrsbetriebe of East Berlin.
Formation
Each set consists of two cars, only one of which has a driving cab. Thus, the smallest operable formation is a four-car train.[2] Up to four two-car sets can be operated together.[1]

History
Twelve sets were lent to the Athens Metro between 1983 and 1985.[2] Class GI trains replaced all Class A1 and A2 trains by 5 November 1989.[1] In 1997, 60 sets were sold to the Pyongyang Metro in North Korea.[2]The train received new features over the years. The automatic next station announcements that first appeared on the BVG Class H trains were implemented in the BVG Class G trains in the early 2000s. A twin LCD advisement displays were also added and since the 2010s, the left screen shows next station information. The GI/1 trains were refurbished into GI/1E trains between 2005 and 2007 giving the outside unibody a full paint livery of yellow. The refurbished interior received yellow poles, new seats and the door handles to open the doors were removed and replaced with a button. The interior of the doors was also repainted gray replacing the oak brown color.
