Since June 2014, the KTX train operates from Incheon International Airport to Busan or Mokpo.

In September 2018, Korail officially announced that they would stop operating KTX to Incheon International Airport due to lack of passenger use.

Before KTX started to run on AREX, all platforms were high-leveled with screen doors.

The KTX started to run, they took away the platform screen doors only at the both end of the side horizontally and turned into low-leveled platform without screen doors.
