Kato 2016-B Steam Locomotive JNR D51 Hokkaido Type - N Scale
 
The D51, with its enclosed cab and shortened deflector, was used until the end of the steam locomotive era, and was designed for the extreme cold climate of Hokkaido.

The JNR steam locomotive D51, affectionately known as "Degoichi," was manufactured in 1935, the largest number in Japan, with 1,115 units manufactured, and was used throughout the country. Many variations were made due to modifications made to suit the region and line, and in Hokkaido, it was characterized by its unique equipment that could be called the extreme cold climate specification. In addition, the D51 was equipped with a device called a "Giessle ejector" to improve combustion efficiency, and was characterized by a flat, inverted trapezoidal chimney, which reduced coal consumption by about 10%, but since the end of the steam locomotive era had already come, only 36 units were modified, and they were concentrated in the Oiwake Locomotive Depot in Hokkaido.
