[4K] Transfer to the Seoul Subway, Line 9 to Line 1 & 1 to 4, Public Transportation in Korea

Weekday morning in November 2020
I transferred to Line 1 at Noryangjin Station on Subway Line 9. I took Line 1 from Noryangjin, crossed the Han River, passed Yongsan Station, and arrived at Seoul Station. Shall we transfer from Seoul Station to Airport Railroad? I thought about it, but I ended the video by transferring to Seoul Subway Line 4.
Line 9 is a relatively new route, but the transfer distance is unexpectedly short in many cases. Noryangjin Station also has a fairly short transfer distance. The transfer section from Seoul Station Line 1 to Line 4 has a pretty red brick wall and is quite impressive.
