Specifications

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 polls, 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.

After the GI class was withdrawn from use on the Pyongyang Metro, they were converted by the Kim Chong-t'ae Electric Locomotive Works to operate as EMUs on the national railway lines of the Korean State Railway, which numbered them in the 500 series. They are frequently seen in the northern part of North Korea, running along the Hambuk Line, the Pukpu Line, and the Manpo Line; they are occasionally seen running as mixed trains pulling regular railway freight cars.[citation needed]
