[Very clear Motor Sound] Seoul Metro GTO-VVVF set 4011 from Myeongdong to Hoehyeon

*this is the first vid I'm releasing from my trip to s.korea, and is also one of a handful of videos without editing
decided to take line 4 and managed to find this GTO-VVVF train, which has quite a nice sounding motor! (probably even better than SIE hehe)
