Lines 3 and 4
While Busan Subway Line 3 was being planned, the planners thought about making what is now Busan Subway Line 4 the 2nd phase of Busan Subway Line 3. However, for several reasons, they have made this 2nd phase into a new line called Busan Subway Line 4.
Archaeology
Compared to Line 3, Line 4 took quite a long time for its construction. There are many reasons for this; however the most significant one is that there were many artifacts found in the construction site of the line, including those from the time of the Three Kingdoms of Korea and the Joseon Dynasty. These artifacts had great historical value, so they caused the completion date of the line to be delayed from its original date of opening in 2008. Some of these artifacts are being displayed inside a historical museum dedicated to this in Suan Station (the museum opened on January 28, 2011).
Car builder
