JGR Class 7010
The JGR is a steam locomotive formerly operated in Japan by Japanese Government Railways. Specifications. The diameter of the driving wheel is 1,067 mm (3.5 feet) while the axle arrangement 0-6-0 is a tender type steam locomotive for a two-cylinder single satellite type freight train. The tender has two axles. The valve system is an Allan type, the safety valve is a SALTER type, and a steam dome is provided on a boiler. It has a rapid injection (pop type) safety valve. In keeping with the style of the time, the locomotive body was  not equipped with a brake device; a brake was provided only for the tender. This form was used with relatively little remodeling compared to the 2-4-0 type tank locomotive imported at the same time. Additionally, it was used for installing the brake device to the locomotive body and installing a salter type safety valve. In some cases, the cylinder cover was also enlarged.
