Gyeongin
The name Gyeongin refers to the Seoul-Incheon corridor in South Korea, and is used as a name for the Gyeongin railway line, the Gyeongin Expressway, and the Gyeongin Canal, all 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" and "Incheon."
