点评：Spotlessly clean both trains and stations, what a joy compared to Metro Melbourne. Waiting times of at most 5 or 6 mins even later in evening. At peak hour, don't rush and worry if you miss one, there will be another in a few minutes, literally. It's easy to navigate the various lines, and there are helpful staff at most stations if you get stuck. Even the locals will help you out. If only our own home town system was half this good!
