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]
Electric systems
The trains are powered by one self-ventilated motor per bogie. Both axles are powered through two hollow-shaft gears.[2]
Interior
The interior features longitudinal seats.
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 North Korea.[2]
Korean State Railway 500 series
After the GI class were withdrawn from use on the Pyongyang Metro, they were converted by the Kim Chong-t'ae Electric Locomotive Works to operate as EMUs on the national railway lines of the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]
