"As for the trains, we rode the cream of the crop, Berlin D-type hand-me-downs from Germany that were planned for scrap until North Korea purchased them back in 1999. These are now claimed as Korean-built. All indication of Berlin manufacture has been removed, and the train numbers have been changed, however, remnants of scratch-tag graffiti from their past life in Germany could still be made out despite the erase attempts. Admittedly, they weren’t as bad as the trolley buses…those things still had the portfolio works of Banksy on their windows."
