I built a fork of OpenrailwayMap (original at https://www.openrailwaymap.org, vector styles at https://openrailwaymap.fly.dev).

The style was built to match the look of the original raster tiles closely, although I added many more interactivity features in the vector variant.

Is is interesting from a style/tile design perspective that the performance tradeoffs choices become very different how and where the tiles are rendered. This is obvious, but it has effects on what is possible on the server / clients visually as well.
