Abstract

Train speed was previously controlled by the wayside signal. But the high speeds on the Shinkansen line made this safety system dangerous, as the train is running too fast to see the signal, and moreover cannot slow down immediately. Trains are therefore operated by means of a single signal inside the cab, which indicates the speed at which the train must run, and operates the train automatically, although the driver has manual control of certain operations such as speeding up and stopping in stations. The article explains the reasons why JNR adopted ATC for the Shinkansen line, and also how it functions.
