Dear Peter, The issue you describe is familiar to me. The UK OSM ways contain a lot of irregular tag combinations like usage=yard and usage=cargo. The last couple of months I’ve been working on these issues (along with adding speed limits) in England, Wales and Scotland. I hope that it is already solving more and more of the problems you describe.
If you want to contribute, I would recommend to install and use JOSM (https://josm.openstreetmap.de/). It allows you to download specific relations/ways/nodes from the OSM database through queries. Another possibility is to search the data you downloaded for specific properties. You can use these features to look problematic properties like “railway=rail -usage=* -service=*”. When you found the ways, you can add the appropriate tags. If you need further help on this, feel free to let me know.
