It is similar to the Korail Class 1000 trains, but before replacing them with screw-type air compressors (YT2000DM1) around 2011, electric generators and piston-type air compressors (C-2000M) were used as they were, and vehicles that went through major repairs replaced auxiliary power supplies with electric generators (MG) to stationary inverters (SIV).
