The KTX (Korea Train Express) operates the route from Hongseong to Asan, traveling at speeds up to 300 km/h. The journey typically takes around 1 hour and offers features such as comfortable seating and onboard services. Alternatively, the Mugunghwa train is also available for this route, which travels at lower speeds, generally around 90-120 km/h, with a longer travel time of about 2 to 2.5 hours. Both options provide a reliable means of transportation, each catering to different preferences for speed and pricing.
