Direction of travel

Some trains on the Hong Kong metro have diagrams like this: the remaining stations on your journey light up (in this case, Mong Kok, Prince Edward and Sham Shui Po) and one set of directional arrows ripple round to show you the direction of travel. There is also a light (not in this photo) to tell you which side the doors will open at the next station. Nice one.
