Directly seeing the lines on the map improves a user's orientantion when they open the app.
Many cities color-code their lines so this is also an important information that is currently completely missing in Transportr.
As this feature is available in mainstream Google/Apple Maps i think this is an important feature that would improve the usability of Transportr.
The screenshot shows the 5 subway lines in Vienna in their correct color, so anyone living in Vienna will directly know which color is which line.
DISCLAIMER: The coordinates for the lines are parsed from the Overpass API. As I'm new to the development of map applications their most likely is a better solution to query the coordinates of transportation lines. This is just a POC.
