Gyeongin
The name
Gyeongin (
경인 (
京仁) in
Korean) refers to the
Seoul-
Incheon corridor in
South Korea, and is used as the name of the
Gyeongin railway line (Gyeonginseon; 경인선; 京仁先) and
Gyeongin Expressway (Gyeongin Gosok Doro; 경인 고속 도로; 京仁高速道路), both of which link Seoul--the South Korean capital and largest city--to nearby Incheon--the second-largest port and fourth-largest city. The name "Gyeongin" is formed from the first characters in the names "
Gyeongseong" (경성 (京成), the Korean form of "
Keijo" (京成), the former
Japanese name for Seoul) and "Incheon" (인천 (仁川)).
