Oh, I actually thought it failed at the first hurdle re switches, but I was wrong about that, so my initial comment and change was incorrect.

I haven't gone back through the changesets, but I think some earlier tagging included public transport tags. I note that iD actually encourages the tags to be "upgraded" to include these.

I've tweaked the alignment to cadastral parcels at the eastern end, improved the way resolution, added a building, and added some extra nodes on the track.

Thanks for your corrections!
