Just saying. I know the intent is to show roads, but subway tunnels under streets are entirely hidden. (This is less of a problem for OSM because of their “transport map” layer, but even that has issues with bus routes covering subways.)

Yes, this problem is a OpenStreetMap-problem. So I draw my subway-lines not direct under the street, but a little bit aside. And too you see better your subway-lines, if you draw not one line, but to lines - one for each track (see in Latina (Cidudad) or in Villa Constitucion in Ardisphere) and at stations the platforms.
If you go in the “histor-style”, you see the metrolines in blue and more prominent.

histor is right. you have to kind of “accommodate” the renderer, by placing your tracks slightly to the side of streets and adjusting positions of stations, etc. I’ve noticed this has to be done even in the “real” openstreetmap with subway lines i’m familiar with. I’ve been experimenting with using the type=route relations to try to semi-automatically generate subway maps. Not much progress so far… best example is for line 1: http://new.opengeofiction.net/relation/4375/#map=15/-24.3302/123.8866

Damn it. You can do what you want on OGF, but do not deliberately lie about location in the real-world OSM.

I’m not sure I’d go so far as to say it’s a “deliberate lie” about location to place a subway line a few meters to one side of a major street that it technically is centered under - both the street and the subway line render to widths that aren’t quite precise to a margin of error greater than the displacement in question. Subway lines seem to render fairly well at high zooms as long as you don’t place them “directly under” the street ways. Double-drawing the lines (which is more accurate, anyway) ensures that they will be offset from an over-lying street. The Manhattan OSM, for example, would benefit hugely from drawing subway routes “as they really are” (with a line for each track which are are often 4 tracks in parallel in NYC) rather than as abstract “station-to-station” connectors. I think the rendering problem can actually be reduced by increased effort at accuracy, since it would be statistically unlikely a true rail centerline is precisely under a street’s centerline.
