A street map and a subway map both describe the connectivity within a city, but even when a human internalizes them both, they don't get subsumed into a single map exactly, rather the human mode-switches between them at various points to stich together a route.

If you doubt this, try visualizing exactly which streets and landmarks are going by overhead as you travel between stations. It is rather hard to do, and as a result people often treat stations more like portals into a parallel wormhole network.

This of course uses literal maps as an exemplar, but similar ones are 'code switching' back and forth between dialects rather than blending them, and visual illusions that can be seen as one image or another, but not both at once.

Idunno, I find if you're somewhat familiar with the more detailed map -- and the subway stations are marked on it -- it comes somewhat naturally. You probably fool yourself a bit if / when the subway lines are very curved, because (I guess) you'll tend to imagine pretty straight lines between stations, but... On the whole, that's pretty much why subways were built in the first place, so I wouldn't think you'll be all that much off
