The koki 50000 series is a container freight car manufactured from 1971

The koki 250000 series was introduced in 1985 after the koki 50000 series was modified to handle 100km/h and 1,200t trains. When it was first remodeled, it was painted in the same red no. 3 color as before, but later the body was painted green for easy identification

When it was first introduced, it was used for high-speed freight trains on the tokaido main line, but after the appearance of the koki 100 and koki 101 series, it was transferred to high-speed freight trains on the tohoku main line along with the koki 350000 series.
