Congratulations, it seems very cool. It's not the same, but I'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. It's nice to see something similar implemented to track the transportation in a…

thank you so much! yeah the data comes in many different ways! just here tfl is diff from national rails i've found llms super helpful tho

Looking at this gave me a renewed (even if brief) sense of appreciation for our society.

Even with all of its problems, for this moment in time our society is operating effectively enough that humans can engineer interesting, beautiful, culturally rich landscapes (cities) in quite a significant size scale.

Cheers to us, in 2026.

Vast majority of those miles were built over 100 year ago.

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.

yeah the trains are meant to feel "underground" maybe the effect needs improving

I wonder how much work it would be to actually handle them being underground/overground at appropriate places? e.g. the District Line and/or Picadilly near Hammersmith. Would be cool!

There's also something wrong with the map alignment. I think the tiles are being rendered with the wrong placement - the underlying map doesn't match reality.
