After the GI class were withdrawn from use on the Pyongyang Metro, they were converted by the Kim Chong-t'ae Electric Locomotive Works to operate as EMUs on the national railway lines of the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]}
