SIGNALLING SYSTEM FOR KOREAN TILTING TRAIN EXPRESS

초록

Automatic Train Protection(ATP) and Automatic Train Control(ATC) form an important part of modern train operation. Because of the long separate history of national railway development, railways improved their ATP systems based on their existing systems that are not compatible to each other. In order to solve these problems, the European Community has established a program to promote the development of a future European Rail Traffic Management System(ERTMS) with the European Train Control System(ETCS) as a main part. In Korean, most of lines have used Automatic Warning System(AWS) named ATS(Automatic Train Stop). Although the ATS system enable the train driver to warn the limited speed of train, the train accidents may occur if the train driver is negligent and do not take an appropriate action quickly. In order to improve the train operational speed in the conventional lines, KRRI(Korea Railroad Research Institute) has been developing the Korean TTX(Tilting Train eXpress) and adapted ATP system, which is compatible with ERTMS and has been installed in Honam line and This paper presents the fundamental design of signalling system which is appropriate for Korean TTX of maximum operational speed 180[km/h].
