I know there are discussions about adding names onto the route maps. I was wondering if we could have some basic geographical markings as well, such as where a river, the sea, or the edge of a town might be as a sort of simple background shading. That would help with orienting oneself along a line, and for route learning would help recall where certain landmarks are. When I sought out one of the lines in google maps to learn about it a bit more, it became a fascinating journey of discovery for places I've never been to. Suddenly a simple line diagram started to have some context. Some basic context on the map would be brilliant.
