Can you remove the perspective and just have a top view? That's pretty much a requirement for me.

Ah you need to go to minitokyo2d.com for that

#83Really cool but I'm not sure what's to be gained by it being 3d? If I were to use this as a daily utility it'd happen on my phone while out and about, so I imagine all the rendering could be a critical loss of performance for such a use case. Also seems like an overly complicated way to organize such a dense amount of information? At least a toggle between 2d/3d would be good
Looks like there's a 2d version[0] but the map doesn't load (expired API key?) and it doesn't show as many lines. Can maybe be revived or adapted for your city by checking out the source [1]. [0] https://nagix.github.io/mini-tokyo/ [1] https://github.com/nagix/mini-tokyo
Looking at the speed at which the trains are moving on that map, I don't think it's real-time though.
Probably an early prototype.

#85Following the author on Twitter [1] has been a treat for me. Even right now, he's building a 3D visualisation of runners for Hakone Ekiden [2] [1] https://twitter.com/nagix [2] https://nagix.github.io/hakone-ekiden/
At that point I feel like they should recreate the track using photogrammetry instead of using wonky satellite images. [0] https://www.gtplanet.net/assetto-corsa-modder-photogrammetry...

#86Where are 3D buildings sourced from? Is it just building footprints from OSM extruded to the height tag value?
Is there an open service (OSM-like) where to upload 3D geometry for buildings? I know wikidata has some, but I wonder if it would be possible to build more recognizable maps with that.

is using Mapbox for this feature.

Re: Real-Time Tokyo Subway Map
#88I can't quite tell whether it even shows where lines go under/over one another and knows that exactly, but regardless, it's a wonderful visualization! I wonder at what level the train positions are known exactly versus approximated? Is there a simple flat / non-3D version of it?

Interfaces used in train operation facilities[1] quite different from this but are similar across systems, and this one is more or less just a visualization. At personal levels, you either type in (time, origin, goal) into a map or a route finder app and get on trains in sequence as the app says, or do a rudimentary graph search in your head[2] and hope you don't hit 10 minute gaps between trains, which happens, but…
For air travel, the stops (airports) are the congested nodes but the way between them (air) has much more possibility.
Trains are limited onto tracks and cannot merge out of the way, so point to point more quickly exhausts route capacity. Stations are less of a constraint.
Trains also lower the cost of transferring; airplane transferring is at best a hassle and at worst an ordeal. Meanwhile, trains can literally stop across the same platform across from each other so you walk a few meters at most. Japan does this a lot, where trains are timed to facilitate such quick connections.

#90Earlier quoted context omitted.
The key is to have a regular interval timetable, with "pulses" to allow easy transfers: http://sydneyferry.blogspot.com/2017/09/six-benefits-of-regu... The Swiss are masters of this. I recently had a complicated 4-leg journey from Zurich airport, from a mainline InterCity train to a rack railway up a mountain, and every single transfer was timed at exactly 5 minutes.
I have never been to Swiss, is every transfer the same difficulty? Having all transfer being exactly the same doesn't make sense to me. In Japan there is a predefined minimum transfer time between each lines, so the timetable use that to coordinate departure (and if incoming train is late, then the designated connecting train will wait that predefined time for connecting passenger)
Switzerland does something called the takt, which I suppose in English would best translate in cycle.
Swiss timetables are calculated so that trains make stops on a very consistent hourly, half hourly, or quarter hour cycle. Coordination points are at major hubs; every train shows up within the same five minute period, so one can walk down the stairs and head to a different platform to catch any possible number of trains that have stopped at the coordinated time.
