Kato 7008-H JR DD51 Late Cold Resistant JR Specification - N Scale
 
DD51 is a diesel locomotive for main lines that represents Japan National Railways, with 649 cars manufactured since 1962. For snowy areas including Hokkaido, the A cold region specification, which features a rotating window, has been deployed.
Among the Hokkaido area vehicles that were inherited by JR Freight, the vehicles that only updated aging parts are called A renewal color, which has a blue body and cream front, and has appeared since 2004. In the later years of the Hokkaido area, JR Freight-affiliated aircraft were gathered at the Washibetsu engine depot, and in 2014, they were all retired with the successor DF200 taking over.
