This graphic map of the United Kingdom rail network obviously has the purpose to communicate train routes across the UK. However, it is the connections between each location that form the country of the UK. As an image alone with no information, the shapes and connections still resemble the border and outline of the UK.
This is a fantastic example of how visual recognition of a country's shape can still be held using lines and connections that do not relate to its borders.
The connections unify the country making it what it is visually, as well as maintaining the significance of the social and patriotic connection between settlements in the UK.
The map has the potential to speak more than just where trains travel between.
