what is it?
The DeRoNi-class (Japanese: デロニ) was a group of four boxcab-style electric locomotives with regenerative braking and the capability for multiple-unit control manufactured by Hitachi in 1943-44, very similar to the Toshiba-built DeRoI and the Mitsubishi-built DeRoI-class locomotives. They were built for the Chosen Government Railway (Sentetsu), who designated them DeRoNi (デロニ) class, and after the partition of Korea were inherited by the North Korean State Railway, where they were known as the Chŏngidu (Korean: 전기두, "Electric 2") class.
