Show HN: Follow London Trains in 3D (ride.nexttrain.london)

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

Ah yeah i tried anchoring to the train with a threshold for panning around i'll try smoothing it. thanks for trying it!

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

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

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

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

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

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.

How do I drive the train? Arrow keys not working :(

The planes were a surprise

I'm curious what the 3D model source is - the Gherkin is kinda weird.

OpenStreetMap - seems to be done with concentric circles, e.g. https://www.openstreetmap.org/way/1365317072 and a dome on top

There is a good wiki page on this: https://wiki.openstreetmap.org/wiki/Simple_3D_Buildings

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.
