I realized that how I depicted the Tobu Railway’s service patterns were kinda…odd and nonrepresentative and needed a little, er, elaboration. So this is one of a few preliminary works rolling round in my head so when JR East timetable revision comes out in March and I redraw the Tokyo map, it won’t be as much of a hot mess as the first one.
The passenger would see something like this (in Japanese, of course) on a column at Asakusa Station, probably.
(That said, I can’t make heads or tails of the service patterns at Ota Station. Does the Isesaki Line have no non-limited-express through trains up there?)
