Amsterdam is a great map to practice your line building skills. Here we show how the metro can be used to move people around the whole city. Since it is inefficient to have 100% metro coverage it is fed by smaller, more localized, networks of tram and bus lines. Sea and air lines have also been thrown in to add an extra dimension but are not at all necessary.
