    The rendering is a bit weird. It's disorienting to have the trains simultaneously underneath the map and occluding it. It also seems like the z-buffer is not being used correctly when rendering the train cars.

    the tracks arent grounded to the map, they slide all over, and would it cool if we could use satellite view

    Congratulations, it seems very cool.<p>It&#x27;s not the same, but I&#x27;ve tried to create a free browser-based app to track bus lines where I live (Brazil), but I had to pause this project, as each city uses a different way to track their public transportation, and it would be hard to gather all the info in a way to be usable in the whole country.<p>It&#x27;s nice to see something similar implemented to track the transportation in another country.

    Like on most other digital maps today, what&#x27;s direly missing is a scale bar.. cool feat though, thanks for showing!

    This is scary. I literally just had a dream last night wishing I could see the metro trains from above the ground in order to follow where the tunnels are under the buildings and all that. Wow.

      Accuracy may vary, but it&#x27;s great to see dreams come true!

    This is frustratingly close to amazing. Obviously you went through all the trouble of pulling all the data from all the trains and displaying them in 3d, but then lock our view on to just one train or one station while all that interesting information zips around in the periphery. The view port needs to be more free form...less on rails.

      I&#x27;ll have a note on this! Thanks a lot! a free form to browse the trains I think is definitely doable whilst keeping it performant

    I&#x27;d love to see a view with all&#x2F;many trains. In London I was constantly wondering what the criss-cross of underground lines looked like.

      I saw a project like that here in hn recently for all uk trains even. it&#x27;d be pretty cool to extend this to support that, busy stations might be visually confusing, thanks for suggestions

    This is a fun idea and interesting implementation. I know there&#x27;s only so much an api can give you, but I&#x27;d love to see anything that gives more information or visuals of the surroundings.
    • mgranados1 hour ago
      thanks! you mean more 3d buildings? I&#x27;d love to explore that or more labels on things along the way?
      • Pigo21 minutes ago
        I&#x27;d assume there&#x27;s better options, but I&#x27;ve worked a lot with cesium. Even it has some interesting visualizations, textures, even weather you can add with it. Anything that could make it feel more immersive would just be cool in my opinion. That just sounds like fun to me.

    using Google Pixel 7a with Chrome Android.<p>while the 3d buildings render properly, the trains&#x27; polygons have a flipped z-order: polygons that are supposed to be layered behind are actually in front.<p>nevertheless, great website!

      tysm for the report ill have a look, tried some things to optimise for mobile, I&#x27;ll check it more

    I guess I’m a train guy now
    • giancarlostoro1 hour ago
      Coworker used to have a specific stream up everyday, apparently he&#x27;d seen a car get pummeled by the train. Every now and then something interesting would be on the train. I saw military tanks and gizmos on one stream, was kind of neat.
    • mgranados1 hour ago
      There&#x27;s planes by the airports too

    Interesting but quite buggy. Example: mouse dragging seems trapped in a fairly small area.
    • mgranados3 hours ago
      Ah yeah i tried anchoring to the train with a threshold for panning around i&#x27;ll try smoothing it. thanks for trying it!
  • fredley5 hours ago
    Very nice, but the map seems to be in the wrong position vs. the trains&#x2F;3d elements.
  • dmazin5 hours ago
    It would appear you are missing the High Barnet branch of the Northern line.
    • jdswain1 hour ago
      Looks like many (all?) branches are missing. Central line doesn&#x27;t have the Ealing Broadway branch.
    • uukelele4 hours ago
      And the Reading branch of the Elizabeth line
      • mgranados3 hours ago
        thanks for feedback i&#x27;ll have a look!

    Appreciate the vibecoded note.
  • kentonv3 days ago
    This is really cool!<p>Quick suggestion: When not tracking a train, the mouse wheel should zoom into &#x2F; out from where the cursor is pointing, rather than the center of the window.
    • mgranados3 hours ago
      thanks! that&#x27;s a great suggestion will implement

    There seems to be some parallax issues between your trip layer and your 3D Tiles layer, but nice usage of deck.gl.
    • taylorius3 hours ago
      Is it not that certain train lines are somewhat deep underground? The Piccadilly line swims with respect to the ground in the centre of town, when it is below ground. Further out where lines are at the surface the routes stick to the ground correctly.
    • mgranados3 hours ago
      thank you! i&#x27;ll have a look

    Having just taken the Elisabeth Line to LHR T5 and sitting here, this was fun. Thanks.<p>Edit: Is there a Repo to look at and learn from this?
    • mgranados3 hours ago
      &lt;3 thanks!! i&#x27;ll clean it and share here sometime soon
  • ohjeez4 hours ago
    This is incredibly cool. I had it open on my desktop for most of the day.
  • tamimio1 hour ago
    Neat! I chose victoria one and it was flying over the buildings!
    • mgranados1 hour ago
      I knew Victoria was fast but not so much! On a serious note it&#x27;s meant to have a sense of being underground that maybe it&#x27;s failing to convey. I&#x27;ll check the line in more detail thanks.

    How do I drive the train? Arrow keys not working :(
    • mgranados3 hours ago
      It&#x27;s just following api data for now. That&#x27;d be a real cool feature for backlog!

    A bit buggy in term of tiles jonctions

    The planes were a surprise
  • philipwhiuk5 hours ago
    I&#x27;m curious what the 3D model source is - the Gherkin is kinda weird.
    • 0l5 hours ago
      OpenStreetMap - seems to be done with concentric circles, e.g. <a href="https:&#x2F;&#x2F;www.openstreetmap.org&#x2F;way&#x2F;1365317072" rel="nofollow">https:&#x2F;&#x2F;www.openstreetmap.org&#x2F;way&#x2F;1365317072</a> and a dome on top<p>There is a good wiki page on this: <a href="https:&#x2F;&#x2F;wiki.openstreetmap.org&#x2F;wiki&#x2F;Simple_3D_Buildings" rel="nofollow">https:&#x2F;&#x2F;wiki.openstreetmap.org&#x2F;wiki&#x2F;Simple_3D_Buildings</a>

    model rough but amazing. i cant do this
  • gowld4 hours ago
    The train paths are drawn on a 2D layer above the buildings, not at z-index that matches the proper 3-D position. So the paths appear to weave around and over the tops of buildings.
    • mgranados3 hours ago
      I meant to make it feel like the tube ones felt &quot;underground&quot; by some metres i&#x27;ll have a look thanks
