Show HN: Follow London Trains in 3D

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.

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

The planes were a surprise

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

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?
