JNR were far-sighted. SHINKANSEN history

It was already difficult for JNR to build the Shinkansen. However, as for the important thing, construction of the DANGAN-TRAIN was continued even in the middle of the Pacific War here. This was said to be useless work during the war in those days. However, it had an unexpected effect later. The economy of Japan revived completely after the Korean War in 1950. Then, the demand for transportation on the railroads of Japan increased rapidly. It already reached the limit. However, JNR were far-sighted. The Japanese company discharged employees after the defeat. However, JNR employed an excellent engineer from the army who lost his job after the defeat of Japan at the time of the confusion. This was useful for the solution of the vibration of the vehicles under high-speed. The researcher of the Japanese warplanes Japan were useful for the solution of the problem of air resistance. In 1955, SHINZI SOGO, the President of JNR, appointed HIDEO SHIMA as the chief of the engineer team. These engineers promoted the plan of the Shinkansen after that. Japan is an island country with many mountain ranges. And Japan is quake-prone and its geology is not good, either. In order to drive a train at high speed, the system which gives power to each vehicle was suitable in Japan. The Electric Multiple-Unit and Diesel Multiple-Unit are suitable for tracks with many curves and slopes. That is because they have a good capability of acceleration and slowdown. The burden of the weight on the track is small.
