Seohae Line reaches Daegok

With this opening, Gimpo International Airport now has 5 railway lines. I guess it's the largest number among the airports around the world. (But, if we include a rail system inside the airport, Charles de Gaulle Airport will also be tied for the 1st with Gimpo after opening rail lines under construction)
