Indeed (hence why I wrote 'For the US, however, you'd want to do
something other than just "downgrading to track"' above). The "One is
to split..." comment is about technically how to do it within an OSM
Carto-like style; I'm not trying to suggest how things should look,

A dashed casing's certainly technically doable (though I suspect you'd
need to fiddle with widths of things to get the visual weight right).
You may to show tunnels (which use a very fine dashed casing - see e.g.
https://www.openstreetmap.org/#map=15/51.5046/-0.0500 ) in a different
way though first.
