Influence analysis to the ATC signal by using sand on the rail in the High-speed Train(KTX)

살사 재료가 고속차량(KTX) ATC 신호에 미치는 영향분석

When the high speed train (KTX) departs from station in the high-speed line, sometimes on board signal disappears, which causes a hindrance of the operation punctuality, therefore, we have a research objective to verify the causes of hindrance and to find an improvement plan. In the process of research, when train left, we applied sand on the rail to improve adhesive power, whose sand has an effect on the ATC(Automatic Train Control) signal wave. We detected & analyzed signal waves which came from detecting device by changing operation condition in accordance with sand material
