Present Situation and Future Tasks of New Train Control Systems
Yutaka HASEGAWA
Development in world railways of radio communication-based train control systems on-boardto sense tarin positions has for some time been at a standstill,just short of theirpractical application,though a great deal of efforts are being kept up.It,however,seems that new turns are coming in several countries with successful identification of pending problems inherent in the mechanism of these systems. In this paper additionally many more things to remain after realization of this pfoject are debated in a future perspective.
