North Korean Patriotic Song - Train of Reunification Runs! (Pochonbo Electronic Ensemble)

The basic story is about this ’Unification Train’, loaded with goods (nylon, silk...) and machinery (farming equipment, tractors...) running through South Korea helping out their struggling southern cousins. This song was written in the 1960s and North Korea was doing better than the South at that time. Thanks to the /r/Korean community on Reddit for helping find the lyrics, and to Baekai and others who helped translate.
