The maglev linked Incheon International Airport Terminal 1 to Long Term Parking, Incheon Airport Administration Complex, Paradise City entertainment precinct, and Yongyu station and Leisure Complex while crossing Yeongjong Island.

[6] This maglev line specifically utilized electromagnetic suspension (EMS) and linear induction motor (LIM) propulsion.

[13] This train was part of South Korea's Urban Maglev Program (UMP) which started in December 2006.

This train system is the result of a development project started in 1989 within the Korea Institute of Machinery and Materials (KIMM).

[14] During the COVID pandemic the line was reduced to operate during rush hours only, departing Airport Terminal 1 Station every 15 minutes from 07:30 to 09:00 and 18:00-19:00.

[15] The line was temporarily closed from 14 July 2022 due to maintenance and repair of the carriages not being completed on time (required every 3 years)[17] as per the Railroad Safety Act.

At the National Assembly Land, Infrastructure and Transport Committee meeting on 22 August 2022, Rep. Heo Jong-sik of Dong-gu, Incheon called for a “plan to reduce operating costs”, as annual maintenance fees hit ₩6 billion (US$5.24 million).

[16] On 17 October 2022, the National Assembly Transportation Committee held an inspection of the Incheon International Airport Corporation.

They received stern critiques regarding the cost; it was revealed that Incheon Maglev required ₩500 billion (US$437.08 million) of investment over the next 10 years.
