This paper presents results on the running test for Automatic Train Protection (ATP) on-board equipment, a research project to ensure the safety and operational efficiency of electrical multiple unit (EMU) type trains. At the Korea Railroad Research Institute (KRRI), EMU type trains have been developed for the speed-up of existing lines and for passenger service improvement where the Korea Train Express (KTX) is not available. Progress has also been made on the operation trial test of 120,000 km with the use of Automatic Train Stop (ATS) equipment in existing lines, for the reliability assessment of the developed EMU type trains. The Ministry of Land, Transportation and Maritime Affairs (MLTM) has decided to accelerate the speed to more than 200km/h for the 6 existing lines including Jungang-line and Chungbuk-line where KTX has not operated. Because of this decision, the train control system is to be changed from ATS to ATP. An ATP on-board unit should be installed in EMU type trains and the operational suitability verified. Therefore, the authors have trial tested the same ATP on-board unit on EMU type trains that were used in the ATP construction project on Gyeongbu-line and Honam-line.
