The rapid growth of domestic industry after the turn of the century also saw a rapid increase in the number of SLs with the number peaking at 5958 in 1946.
In addition to locomotive-hauled trains, EMUs also began operating on the electrified lines. JNR's first long-distance EMU started operation on the Tokaido Line between Tokyo and Numazu in 1950. In 1958, JNR started operating express trains with a maximum speed of 110 km/h between Tokyo and Osaka. Due to Japanese track standards, the multiple unit system with motor cars coupled to form a train, was preferred over the system using a heavy locomotive at the head of the train. From the viewpoint of terminal capacity, suburban EMUs also had the merit of dispensing with shunting of the locomotive.
