Hmmsim 2: Jangam to Cheongdan in Full Speed! (서울 지하철 7 호선 익스프레스에 오신 것을 환영합니다)

When you can ride the train from Jangam Terminus Station to Cheongdam Station just in 12 minutes (normally you need at least 40 minutes). We only stop at the first and last station. Of course not in a real life, it's taken from an Android game, Hmmsim 2.
