deck.gl based visualiser of the TFL Api + National Rails to be able to track (with minimal drift) a train along the way in London and to the nearest airports. If you pick one from any platform in https://nexttrain.london basically you can share your train journey along the rails. Build to test Cloudflare workers and their infra along with deck.gl performance that is incredible in my opinion.

A bit buggy in term of tiles jonctions

Interesting but quite buggy. Example: mouse dragging seems trapped in a fairly small area.

I'd love to see a view with all/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'd be pretty cool to extend this to support that, busy stations might be visually confusing, thanks for suggestions

There seems to be some parallax issues between your trip layer and your 3D Tiles layer, but nice usage of deck.gl.

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.

It would appear you are missing the High Barnet branch of the Northern line.

Very nice, but the map seems to be in the wrong position vs. the trains/3d elements.

Having just taken the Elisabeth Line to LHR T5 and sitting here, this was fun. Thanks.
Edit: Is there a Repo to look at and learn from this?

This is really cool!
Quick suggestion: When not tracking a train, the mouse wheel should zoom into / out from where the cursor is pointing, rather than the center of the window.

This is incredibly cool. I had it open on my desktop for most of the day.

It's just following api data for now. That'd be a real cool feature for backlog!
