Description

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.

20 comments analyzed.

Competitors mentioned: Cesium, Google Maps Tiles API, DB (German railways)

Concerns raised: Map tile alignment incorrect - doesn't match reality, Jarring/disorienting transitions between train selections, Z-buffer rendering issues with train cars occluding map, Tracks not grounded to map, sliding around, Trains simultaneously underneath and occluding the map visually

Feature requests: Smoother eased transitions between train selections, Realistic 3D buildings using Cesium or similar, Handle underground/overground rendering at appropriate locations (e.g., District Line near Hammersmith), Satellite view option, Scale bar on map
