Seoul Subway Line 4 (dubbed The Blue Line) of the Seoul Metropolitan Subway is a long line crossing from the southwest to the northeast across the Seoul National Capital Area. The southern portion of the line is divided into the Gwacheon and Ansan Lines, but this does not affect the trains which run on it, most of which run all the way from one end of the line to the other. The southern terminus (Oido) is in Jeongwang 4-dong, Siheung City, and the northern terminus (Danggogae) is in Sanggye 4-dong, Nowon-gu, northern Seoul.

The Transportation and Construction Committee of the National Assembly has approved that the northern end of Line 4 will be extended from Danggogae to Jinjeop, Namyangju. Construction will begin in 2015 with completion date in 2019.^[1]
