The name Gyeongin refers to the Seoul-Incheon corridor in South Korea, and is used as the name of the Gyeongin railway line and Gyeongin Expressway, 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)).
