It was challenging to come up with an original layout that is more efficient for showing relationships between lines and shared stations.
When using this design to find a route between two stops that have more than one possible route, it isn’t possible to identify the shortest route, but it is still useful in determining the route with fewest transfers.
In earlier iterations, some transfer stations had the line icon on the right, which I decided wasn’t intuitive enough, and added an extra layer of complexity when laying out lines and stations.
