Fictional metro network for the city of Tallinn, Estonia. I made two versions: one more schematic and one that shows the real distances between stations.
The icons for the brand have been made following Brand Estonia guidelines, and the typeface is Aino, used for the country's graphic identity. The corporative color for the fictional network is Estonian Blue (#0000F0).
Train and tram lines, however, are not fictional. I chose to show them because it's a remarkable transport system in Tallinn that is used by the metro lines I created as reference for the paths, as I am not a Tallinn citizen. Urban bus lines are not shown because they share many paths with the metro lines and it would be confusing, besides there are many of them.
