It seems that the Twitter post "train busan 2" does not relate to a maintenance report feedback to public flat house. It is possible that the user is simply expressing their excitement about taking the train or bus in Busan, or it could be a completely unrelated statement. Without more context or information, it is difficult to determine the exact meaning or purpose of the post.
