Yes, thanks! It now makes sense, but I think it's very unsatisfactory visually. The divided segments make it look like the service has some break between stops, or this is very puzzling. And the "O"s mixed with the dividing lines and the subway line letter are highly confusing.

And by the way, for his legal case, if there was anything to point to the argument of derivative work, this would be it. It's clearly copying (because it's so confusing) the broken line segments style in the map you just linked.

Broken line is pretty common for partial/variable service.

For example, here it is on a philly trolley map: https://www.septa.org/maps/trolley/city.html

And you can also see the same sort of thing on this BART map: https://www.bart.gov/system-map

I agree, but I think there's something odd about the way he's put the segments in his map. Maybe the divisions need to be bigger breaks or something.
