The big question here is whether or not to model underground lines directly as nodes, or
implicitly as properties on relationships. If you model them as nodes, then you might have

This is quite a busy model, and your graph will quickly become very complex if you try to
model multiple lines running through multiple stations. Alternatively, if you model under-
ground lines as properties on relationships, then your graph is much simpler— figure 2.14
shows two stations connected by two different lines.
