Suin Line
For the former Suin Line, the Korean National Railroad built a narrow gauge steam locomotive, the KNR160 diesel car (also known as the Niigata/Kawasaki Diesel Car), and the KNR18000 passenger car. One KNR160 car (later renumbered KNR9160) and two KNR18000 car are preserved at the railroad museum in nearby Uiwang.
