On train, it's been inconvenient to travel from Seoul to northern part of east coastline of South Korea.
But, completion of the line will solve the problem.
When Gyoengchun Line(Seoul-Chuncheon Line) was renovated to be electrified and doubled tracked in 2010, I didn't know why the line had to be renovated.
After reading this article, I found that the reason was to make the line high speed rail.
