hello, Jeroen. I noticed your edits on a couple of lines. After posting here, I changed
the Shrewsbury-Chester line, which immediately provoked a discussion on whether this was a
main or a branch line
https://www.openstreetmap.org/changeset/85440239#map=10/52.8533/-2.9105. There doesn't
seem to be much consistency in these classifications. This route now appears on more zoom
levels on OpenRailwayMap.
This line does not have any relations apart from a route=train one for Chester-Wrexham as
part of WCML to Euston. The neighbouring Crewe-Shrewsbury though has 2 route=tracks. This
seems to me to be a good way to group ways together, but doesn't appear to be
consistently used either. route=train is nice to have, but I would imagine is a large
amount of work to maintain, as services, unlike tracks, change frequently.
I've been looking at Overpass Turbo to familiarise myself with the API. Using 'out
tags' looks like a good way of limiting the output to just a list of which tracks
don't have a usage tag. I'm reluctant to install Java just to use JOSM, but may
well take a look. Thanks for your suggestions.
