The SY class locomotive is the one that modernized SMR Mikaro(Mika-6). It uses it for light cargo and shunting. It is conceivable that this locomotive is almost same with Mikaro. This locomotive built it from 1960. And it continues to be built even now. Now it is used in various place of China. This class locomotive that built newly was exported in America and Korea.

I do not have data of SY class. The data of Mikaro is displayed due to a reference.
