It’s neither a technical issue nor a personal issue.
As each rail is drawn individually, and furthermore each rail has its own railway=halt-node.
In the underground there are in fact 4 subway-rails, which I wanted to draw individually as well, and on the area in front of the station-building there are in fact more than 2 stops.
What a luck, not every bus_stop ist rendered with it’s name…
If I remember everything correctly there are 17 platforms (with its own rail) for regional trains and about 19 stops for local transport (including buses)…
The only point I would agree to you are those two railway=…-nodes having no rail under them. They’re more or less useless, but I think they’re used for the relations of the regional transport.
I actually would call it a rendering issue, as imho every stop needs a name tag. The ÖPNV-Karte renders it quite well, but also only if you’ve no high zoom level.
The individual nodes on each railway line should be tagged as railway=stop, not railway=station.
Plus there should be one node or area tagged as railway=station. That is what the wiki seems to say anyway: http://wiki.openstreetmap.org/wiki/Railway_stations
There are also proposals for a “stop area” relation to group these all together.
