More than 2 million trips are made daily on the Seoul Metro. The Metro system is comprised of 9 main lines that reach the farthest corners of the Seoul Metroplitan area. It is one of the most efficient and extensive subway systems in the world. Over 70% of the subway lies underground and only moments of above ground visibility bear rider witness to the cityscape.
I spend my Tuesday's circling Seoul on the 'inner-cirle line'. Stretching for more than 60kms this trip in three segments takes nearly 2 hours. Raised track platforms reveal the city in small fragments. The visibility is but momentary as trains dive quick to metric depths below ground. I view the city in small glimpses and when submerged imagine the city above; keeping time with the speed of train below.
