The Gimpo Gold Line in northwestern Seoul opened on 28 September. It has 10 stations and is just under 24km long.
The new line connects Gimpo International Airport to Yangchon station further northwest and offers connections to Seoul Metro lines 5 and 9.
Stations, nine of which are underground, are equipped with platform screen doors.
The 2-car vehicles were supplied by Hyundai Rotem and the signalling is by Nippon Signal.
The new line is operated by Gimpo Goldline Operation, a subsidiary of Seoul Metro, the South Korean capital’s main metro operator.
After the Shinbundang line and Ui-Sinseol LRT, the Gimpo Gold Line is the third fully automated metro line in Seoul. There are also fully automated lines in three neighbouring cities: Incheon, Uijeongbu and Yongin. Other such lines in South Korea can be found in the southeastern cities of Deagu and Busan.
