This is really cool. I'm fairly impressed with the maps of the London underground, although there are some oddities in Octilinear mode. It's also missing quite a few Overground services.

It's really nice to be able to switch seamlessly between a Geographic, Octilinear and Geo-Octilinear view of the maps, because each of them tells you something useful. I would use this if TFL added it to their maps app.

Really cool! Very impressed by the results thus far, but thrlere is also some room for improvement. Probably caused in parts by parsing, and in part by input data quality.

- Taiwan has an insane rail network of a few hundred lines - half of the streamlines in Amsterdam are tram 7, apparently it takes you everywhere. - there seems to be an assumption all lines stop on all stations they pass - quite a few regional Train lines are committed in the Netherlands

And finally I woul love a bus version too!

Keep up the good work

It seems like it's missing most of Tokyo? Granted, Tokyo has a blended commuter / subway through-service system (eg, Fukutoshin-line trains continue into the Toyoko-line), but those trains don't seem to show up in either Rail or Subway views.

It is missing most of Tokyo. All they did is look at the subways, specifically the Tokyo Metro system, and maybe a few other lines. The JR rail lines aren't on there, and no transit map of Tokyo is complete without those. The Yamanote line, in particular, is a crucial piece of Tokyo's transit infrastructure, and it's perfectly normal for people to transit between the underground Tokyo Metro and above-ground JR East lines.

Most likely, they just left out the JR Rail and other lines because the map is way too complicated with them, or perhaps it broke their algorithm.

They also didn't show the entire Tokyo metro area, which is much larger than this and includes Yokohama. It's understandable, though: the entire Tokyo metro area is enormous (though perhaps not compared to many American cities like Phoenix, if you just look at land area, but those cities have nowhere near the density of Tokyo), and a map of the entire thing is usually too complicated to bother with, so zoomed-in maps are more useful. This one is showing central Tokyo (the part encircled by the Yamanote line) and parts not too far from it.
