Three new stops opened on the Bundang Line
this week recently, part of a plan to eventually connect to Line 1 in Suwon.
The new(ish) stops are Guseong, Singal and Giheung, opening up Yongin as a convenient new area for Bundang residents to work and play.
The Bundang Line is in yellow on the pictured map.
On a related note, Popular Gusts dug up a 1988 article about Seoul’s plans for the metro. Notice that 24 years ago, Seongnam was very peripheral.
