[Introduction to the Contents]
The conversion of long-distance trains into electric trains is an important issue in the power modernization of JNR. In 1950 (1950), 80 series Shonan-type electric trains were introduced, and in 1957 (1957), 91 series Tokai-type electric trains with lighter body and improved running performance were introduced.
By making use of this technology, the "Business Limited Express" was planned to connect Tokyo and Osaka in 6 hours. The series 20 electric trains for "Kodama" were put into operation in 1958 (1958) as a result of the introduction of various new technologies.
This Series 20 electric trains (later 151 to 181 series) recorded 163km/h in high-speed tests, the highest speed in the world of narrow-gauge railway, and the Odakyu 3000 type SE train, which was the most advanced high-speed train at that time. As a result of the introduction of various new technologies, the series 20 electric trains for "Kodama" were put into operation in 1964 (1964).
This book explains the history of the technical and design development of "Kodama" series 20 electric trains, which can be said to be the peak in the history of electric train development after the war.
