A look at Seoul’s metro-map is quite intimidating because it contains over a dozen subway lines (I counted 17, not including Everline) in a wide-reaching network. However, it doesn’t stop authorities from planning further extension and improvements of the system. End of July Seoul announced that they want to build 10 new subway lines in order to give every citizen the possibility to get on a subway within a 10 minutes radius from their home.
Gyeonggi-Do Will Also Expand Rail Network
Before we go into details of Seoul’s plan, I just want to mention that Gyeonggi-do will expand their subway-network as well. 9 lines with 163 km of rail are going to be build until 2020. The costs are estimated to be 5.8 trillion KRW. Their main motivation is to increase the model share of rail transport from 8.9 % to 17.1 %. You can find a map of the new lines for Gyeonggi-do here.
Actually, the magic number for Seoul is also 9! I mentioned 10 lines but 1 of them is an extension of Metro Line no. 9. Even though it isn’t a completely new plan, the plan contains still some surprising element: The former mayor of Seoul Oh Se-hoon intended to build seven new lines. After Park Won-soon became mayor of Seoul he postponed the plans, which is usually a sign that they were never supposed to be build. Now the city government published that they are going to build ten new lines. Six of the lines have been in the plans of the former mayor. The line, which was scratched, was the DMC-Line, a 6.5 km tram line from Susaek Station to the World Cup Stadium. Read more of this post
