manvels: The ad is intended for a German audience, so I don’t think it’s unreasonable to limit the routes shown to only those that run within the country.

whynotexpressyour-self: Uh, maybe?

Stoddblog: Thanks! I am constantly amazed at how many people love transit maps like I do.

immigrantstories: Thanks for the info - Seoul, Toronto and Vienna are on the list of maps to review! I find Wikipedia is good for information about each system, but not so great for maps - they can be of very variable quality.

daniibp23: I bet it is! Added to the list!
