Here's a zoomable 3D model of the world's busiest train station, Shinjuku in Tokyo:

https://satoshi7190.github.io/Shinjuku-indoor-threejs-demo/

3.6 million passengers per day. Wikipedia:

The main East Japan Railway Company (JR East) station and the directly adjacent private railways have a total of 35 platforms, an underground arcade, above-ground arcade and numerous hallways with another 17 platforms (52 total) that can be accessed through hallways to five directly connected stations without surfacing outside. The entire above/underground complex has well over 200 exits.

    Throwing in Japan into random topics in trains feel somewhat unfair. Most train fact sheets fail to include most Asian nations except Japan, often missing even Korea and Taiwan.

    Commuter trains in many East/Southeast Asian cities like Shanghai has developed to levels comparable to Tokyo. Trains in some Central Asian cities such as Mumbai were also always notorious for congestions. I think those should also be considered more often and at greater depths, Fermi estimated if need be, than we would be just keep dropping random Shinjuku facts left and right.

    • decimalenough 5 hours ago

      We have stats for India, and they're no match: Kolkata Howrah gets about 1M pax per day, Mumbai CST around 670k. Nothing to sneeze at, but still several million (!) less than Shinjuku.

      China has numerous airport-sized stations that handle huge volumes of long-distance passengers, but I'm not aware of any single commuter hub remotely the size of Shinjuku. Partly this is because of the economic system: Chinese trains are all state-run and centralized, while a large part of why Shinjuku is so busy is that it's a hub for numerous private railways as well.

      Is India considered central Asia? I've always seen it referred to as south Asia, and former Soviet countries like Kazakhstan have been referred to as central Asia. I think India is east of these "central Asian" countries. Perhaps this is all a bit of pedantry.

This is amazing, seems really detailed and leveraging official sources too, nice job!

Since the author seems to be Catalan, I'll shamelessly plug a Metro-station-relevant event that is ongoing right now in Barcelona:

There are many "ghost" metro stations in Barcelona that been popular (at least used to) urban exploring destinations. Two of those, Gaudí and Correus, are now opening to the public via tours, if you register at https://obrimelmetro.cat

I've only visited Gaudí in a unofficial capacity like a decade ago, and haven't yet done the new tours myself so can't vouch how interesting they are, but seems there are only 5000 open spots in total. It seems like one of the tours is even during the night, so you get as close to the urban exploring experience as possible without having to run across active train tracks :)

Wow, very nice project.

The ones in Zürich are not actually metro stations. They where built to be, but then the city voted against a metro. The stations that were already built were converted into tram stations. There where some complications like that fact the the tram is almost too tall to fit. The pantograph is almost fully compressed when the tram enters the tunnel.

The trams also switch to the left side as the doors are only one side.

    I'd love to know why you'd vote against having a metro.

    • joshvm 7 hours ago

      Zurich does pretty well with light rail, trams and buses. Public transport is very good there. Two more reasons are that the city isn't that big, so you're in easy walking distance of some sort of connection, and the terrain isn't ideal. A good chunk of the population live up steep hills which are well-served by the tram system. The airport is also very well-connected by bus/tram/rail, and only 10-15 minutes to the centre.

      That said, I would have loved to see HBf on this website.

      I really like urban places with public transport on the street. It leads to less cars and more pedestrian friendly streets. Also I think for small distances (Zürich is not that big), I rather ride a bit longer with the tram than going down to a deep metro station, especially in hilly places.

      Buses also have the doors only on one side usually, if you're just running trams on the surface in traffic you'll probably only need them on the pavement side of the vehicle. It's just got weird in this case the assumption the choice was made on changed after they already had a fleet.

        It’s highly likely that Russia already has detailed models of every stations in Ukraine. If they didn’t before the war, they do now. Mapping public infrastructure doesn’t require a lot of spying.

        But you have to understand that information control during war requires a shift of mindset. It’s better to start controlling everything which could be used by the enemy even if they probably already have it than try to establish complex rules. It gives good habits to people.

        Of course they know where the stations are. But they don’t necessarily know the precise local of all the underground tunnels, exits, mechanical rooms, equipment, etc. The underground network is far more complex than what the consumer map hanging on the wall in the station shows.

        • diggan 5 hours ago

          During the Cold War, Russia managed to map huge parts of the world, sometimes with higher quality and more accurate measurements than the countries themselves! Especially noteworthy considering that some of those countries (like the UK) were trying their hardest to prevent those sort of maps being made in the first place, yet the Russians ended up with better maps of the UK than UK themselves.

          Considering that that happened decades ago, I'm guessing their (and others) capability of doing those sort of things have only improved, not gotten worse. But that's just me guessing.

          • walterlw 23 minutes ago

            I'd like to remind you that Russia is not the USSR. Surely the technology has significantly improved since, but some capabilities are definitely lost. One example is them not being able to build more strategic bombers.

A very cool project, and a great resource for people with reduced mobility - I semi-regularly use Transport for London's station drawings (linked on this website) over the official accessibility map, which doesn't differentiate between stairs and escalators for example.

jddj 8 hours ago

Very impressive work.

I also learned something, which I'd always wondered cynically but never thought to investigate. The walking connection between lines at some stations in Barcelona seems so long as to not make sense, but it's explained here that at the time the different lines and stations were dug and extended independently by different companies.

> Among the reasons for having such long corridors [in Barcelona] is the lack of planning or the vision of the metro network as a bunch of individual lines. As an example: line 1 and line 4 were extended to Urquinaona in 1932, but both lines were not connected until 1972, as they were originally operated by different companies.

  • FearNotDaniel 7 hours ago

    In London that’s also mostly true due to the patchwork history of different companies building different lines… however when King’s Cross/St Pancras was redeveloped a few years ago the “official” interchange route between Piccadilly and Victoria lines became much, much longer - minutes of walking compared to seconds. This site doesn’t cover that station, but does link to TfL’s own diagrams via IanVisits, and the reason is clear: at one end the platforms of both lines are almost touching - and I believe that shortcut staircase is still there if you ignore the signs and know where to find it - but the tourist friendly route is much more circuitous, going up to the mainline station and back again. I assume it helps to relieve congestion in an extremely busy station, I remember more than one occasion when they just have to close entry to the platforms during rush hour due to overcrowding.

  • StopDisinfo910 5 hours ago

    The issue with Châtelet - aside from how crowded it is - is that it’s two stations masquerading as one, same as Montparnasse-Bienvenüe.

    Once you know what’s on which side and that the directions in the main hall are purposefully made to have you meander for flow control and you can just cut through, it gets a lot more manageable.

This can probably only be done during the design phase otherwise to costly to ever change if it's even possible.

hbarka 6 hours ago

This is a remarkable feat. Amazing.

I’d like to add an interesting metric: density of subway/metro stations as measured by number of stations per square kilometer.

In European cities,

City, Metro System, Stations, City Area (km²), Density (stations/km²):

1. Paris, Metro de Paris, 244, 105, 2.32

2. Berlin, U‑Bahn only, 173, 892, ~0.19

3. London Underground (London Tube), ~270, 1,572, ~0.17

4. Madrid, Metro de Madrid, ~300, 605, ~0.50

Paris takes the lead, not just in Europe but globally, with ≈2.32 stations/km². Madrid has a dense network too (≈0.50), though well behind Paris. Berlin (U‑Bahn only) and London have much lower densities (~0.17–0.19). Rome’s iconic metro is relatively sparse in terms of station density compared to other major European and Asian cities.

Here’s how European and Asian cities stack: 1. Paris (~2.32 stations/km²) 2. Seoul (~1.27) 3. Madrid (~0.50) 4. Tokyo (~0.46) 5. London (~0.17) 6. Berlin (~0.19) 7. Hong Kong (~0.09) 8. Shanghai (~0.06) 9. Rome (~0.057)

Seoul is highest among major Asian metro systems in terms of station concentration, making it the city in Asia with the densest metro network per square kilometer. Seoul has 768 stations in its metropolitan subway system spread across the city proper area of 605 km². By comparison, Tokyo’s combined metro (Tokyo Metro + Toei) has around 286 stations over ~621 km, giving a density of about 0.46 stations/km². Beijing has 523 stations but the city covers about 16,411 km²—yielding a much lower density (~0.03 stations/km²). Shanghai’s figure fluctuates due to rapid expansions: 409 unique stations from early 2025 data.

In addition to density, another interesting metric is the number of street-level entrances (exit/entry points). Counting just stations ignores how many access points are available to the public. More entrances = better coverage, shorter walking distances, improved accessibility, especially in dense urban zones. Examples from Paris are: Saint‑Lazare station (Lines 3, 12, 13, 14) has 11 entrances. Hotel de Ville (Lines 1 & 11) has 7 entrances. Madeleine station (Lines 8, 12, 14) has 5 accesses with 7 separate entrances. Alesia station (Line 4) has 6 entrances. Opera station (Lines 3,7,8) has 3 main entrances.

On average, Paris Metro stations have approximately 3–6 street-level entrances, with major hubs having 7–11. Paris doesn’t just have many stations, it maximizes them with multiple entry points, making its system exceptionally accessible over its territory. Seoul also scores similar in accessibility due to its exit-rich stations, especially in dense areas. Other major metros (Tokyo, Madrid, London) lag when entry points are factored in.

I did not include US cities but I believe New York City might be notable.

    > 4. Madrid, Metro de Madrid, ~300, 605, ~0.50

    > [...] Madrid has a dense network too (≈0.50), though well behind Paris.

    As a native of Madrid, I must point out that using the nominal surface area of the municipality of Madrid (~605 km²) is misleading for these purposes due to the Monte del Pardo [0] and Soto de Viñuelas [1], two fenced off forest areas covering around 180 km² between them. The impact of these areas on the nominal surface area of the city is visually obvious when you compare the outlines of Madrid and Paris administrative areas:

    + Madrid: https://www.openstreetmap.org/relation/5326784

    + Paris: https://www.openstreetmap.org/relation/7444

    As a result, the relevant surface for estimating the density of Metro stations in Madrid should be at most ~425 km². While one may arguably also want to exclude the Bois de Boulogne and the Bois de Vincennes from the surface area of Paris, even the "de-Pardo'd" surface area of Madrid still contains significant non-urban areas such as the Casa de Campo forest, large non-built-up areas, and even most of its airport.

    (In any case though, after this pedantic "well ackshually", I must also point out that a few Madrid Metro stations actually fall outside of its municipal limits. I would get out more, but I live in a town without a Metro)

    Is Paris 6 times smaller than Madrid and 15 times smaller than London? Seems suspicious to me. What exactly is the boundary of this "area" and how does it relate to the subway network?

    • Mordisquitos 2 hours ago

      A significant proportion of the administrative area of Madrid is covered by fenced-off forests. Plus it covers other swathes of non-developed land and even most of its airport. The administrative area of Paris proper, on the other hand, is fully urbanised. See here for comparison:

      + Madrid: https://www.openstreetmap.org/relation/5326784

      + Paris: https://www.openstreetmap.org/relation/7444

      London is a whole different animal. While Madrid and Paris are arguably "similar" cities in terms of urban design and residential density, London and UK cities in general are completely different.

ant6n 8 hours ago

Love this project. Back in my transit blogging days, one of the themes was short and long transfers. And here this idea immediately starts surfacing just looking at the stations - the crazy mazes with long tunnels are cool to explore on paper, but suck for actual transfers. It adds slogs in the middle of the trips, and kind of discourages transit use because trips seem longer and more work.

When scrolling down, the author actually includes a long discussion on the best possible transfer layouts! Many of the terrible stations over time are of course historically grown, evolved over time, and weren't the result of some maniac evil genius deciding to create miserable transfers. Systems are built sometimes over a hundred years, so a later station is added mostly where it can fit, not a as a result of some master plan.

But there's also ways to deal with these issues, which can be found in Berlin.

1) for the recently opened "Unter den linden" station, which is a transfer between a new extension (u5) and a 100-year-old line (u6), a station on the old line was actually moved by 180m so that the transfer would be good. (That is, the old station was closed and a new station built a bit a distance away)

2) in general in Berlin, especially after WWII, a lot of the subway construction followed a very long term master plan (to the extend that West Berlin actually planned a network for all of Berlin, even though the East was in another country behind the iron curtain). When stations were built, the planners "knew" it would be a transfer some day, so they added in accomodations ("Bauvorleistung" or preparations ahead of actual construction), often whole station shells for the future line it would connect to. This resulted in a lot of short transfers even when lines were built decades apart. And it also resulted in a bunch of ghost stations, which have yet to be connected to lines.
