Abstract
An ATC (Automatic Train Control) system with an autonomous on-board device had been developed to deal with flexibly : the variation of train performance; improvement of riding comfort; train speed-up; and reduction of headway. The brand-new ATC system is already put in service. Then, an integrated train protection system was developed by unifying said ATC-function wayside and electronic-interlocking function within a device. Developed technology is expected to reduce the replacing cost with aged signal equipment and also to improve the transportation performance of railway lines.
