I am struggling to come up with a proper layer style for a rail network extracted from OSM in QGIS. I just want active rail so I choose the "rail" tagged features (rule-based rendering). But since every track is a line and escpecially within cities, there a sometime 5 or more tracks close to each other so the symbology looks pretty ugly like in the screenshot. What could I do besides, deleting the features I do not want to be shown (which would mean a lot of work)?
Some other things you could consider to reduce the number of lines shown is to use the "service" tag to filter out some of the shorter segments like small spurs and internal yard lines:
- service = siding: Relatively short lengths of track, running parallel to (and connected to) a main route
- service = spur: Relatively short lengths of track, built to give one company or entity access to a main or branch line.
- service = yard: Tracks within railway company operated marshaling or maintenance yards.
