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
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.
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.
Edit: Is there a Repo to look at and learn from this?

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