Starting from April 2011, the new Jeolla KTX service will share tracks with the Honam KTX until Iksan, and diverge from there to reach Yeosu along the Jeolla Line. Korail also plans to run some through KTX services to Incheon International Airport on the AREX line from 2012. The planned travel time between Incheon International Airport and Gwangju is 3 hours.
