(Planned subway museum). One of the newly built subway stations on Line No.9 will have a subway museum. The museum will show 30 years of subway history by exhibiting old railroad vehicles, train models and related books. (News from 2006.) Since 2010 (?). Reference: korea.net/news.
Some trains have buzzing noises (completely different than Paris) that sound like "le-le-le-le-le-le-le-le-le-le" until the doors close. Some just have a conductor standing outside and the conductor closes the doors when nobody in in the way. Next-station announcements in Korean and English.
