First Diesel Locomotive Trial in Japan

August 17, 1925, saw Japan's initial diesel railcar demonstration on the Tokyo-Yokohama route by the Japanese Government Railways. Designed with German influence, the 100 hp unit reached 60 km/h, addressing steam coal shortages post-WWI. This trial laid groundwork for Japan's high-speed rail future, reducing emissions and enabling rural branch line viability. Key engineer Shigenosuke Ushioda oversaw the project, which influenced later DMU developments amid the Showa era's industrialization.
