Spelled as A’REX to increase its significance as a brand name, AREX is essentially a rapid transit service in South Korea that links the capital city of Seoul to the Incheon International Airport as well as Gimpo Airport. The section between these two airports was opened in March 2007, and ultimately in December 2010, a section was opened extending the lines to the Seoul Station. Owned by the Korea Rail Network Authority and operated by the Airport Railroad Co. Ltd, the AREX metro service covers 11 stations and spans over a length of 61 km.
After its huge success in the city of Seoul, the city of Incheon requested the construction of three new stations. This year the AREX pass through the Geomam Station, ultimately connecting to Incheon Subway Line 2. Interestingly, the South Korean Government wants to further amp up the service by reducing the travel time from Seoul to 95% of the country by the year 2020.
