Abstract

ccording to the airport railroad linkage facility expansion project constructing a connecting line to the airport railway and improving the signal system and Gyeongui Susaek Station, a high-speed train is able to run directly from Gyeongbu and Honam to the airport railway. According to mixed operation of high-speed Korea Train Express (KTX) and Airport Railroad Express (AREX) trains, to establish ERTMS/ETCS L1 ATP to operate the KTX train, the signaling system of the AREX train is the same as the existing ATC/ATO, but its operation became impossible because the high-speed train causes mutual interference between the "high-speed train (KTX) and AREX ground signaling equipment" and between the "AREX train and KTX (high-speed train) ATP ground equipment." Thus, it was necessary to have a supplemental technical interference analysis comparing the characteristics of the AREX beacon and the KTX balise. So, we resolve the problems of mutual interference between the "high-speed train (KTX) and AREX ground signaling equipment" and between the "AREX train and KTX (high-speed train) ATP ground equipment" with a test using an actual train, and we confirm the technical validity with three types of test module.
