Use of man_made=gantry for railway signals.
The tag mostly describes, gantries used on highways, however a gantry is an overhead structure in general and these used for railway signals aren't any less of a gantry than highway gantries (duck tagging) to the point where and the linked Wikipedia page and the very proposal of this tag listed them too. I'm asking this because most of my use of man_made=gantry is for these railway signals. --ManuelB701 (talk) 16:22, 1 December 2024 (UTC)
- AFAICT, railway signals usually use railway=signal, perhaps with railway:signal:position=bridge (or similar) to indicate they are on signal gantry overhead the railway track. Also you might be interested in power=catenary_mast on railways. --mnalis (talk) 00:07, 2 December 2024 (UTC)
- Yes but with signals in particular, you aren't mapping the structure itself, only where the signal is located and is equivalent to saying that power=catenary_mast is unnecessary because a railway=milestone with railway:milestone:catenary_mast=yes is existing or that mapping shelters, benches and waste bins on PT stops are unnecessary because the information can already be deduced by the public_transport=platform tags. That's why I specifically asking this because I'm going beyond this barebone mapping (and it also helps the positioning of the signals themselves too). --ManuelB701 (talk) 15:46, 2 December 2024 (UTC)
- No worries, I was pointing out those tags as you didn't mention them, so I didn't know if you were aware of them. If you have already mapped catenary masts and signals with their positions, and want to map gantries in addition too, it seems fine to me personally. There seems to be some such uses already (e.g. see this (slow) overpass). I'd suggest opening a topic in community tagging forum and linking here for possible alternatives and/or more feedback on using man_made=gantry on railways and updating its wiki. --mnalis (talk) 18:49, 6 December 2024 (UTC)
- man_made=gantry is a structure that should be usable for all features. The same term is used in railways.
- It even referred to those with railway=signal_box building=* https://www.lner.info/forums/viewtopic.php?t=12934
- "Signal bridge" is a US term, and they won't be considered a man_made=bridge in OSM otherwise. So British English and common language should be followed. The result is clearer. https://en.wiktionary.org/wiki/signal_bridge
Using railway:signal:position=bridge to "means the signal is located on a signal gantry overhead the track" is confusing. It could mean on another actual bridge conveniently, rather than dedicated structure. The definition and overlap against railway:signal:position=overhead needs to be cleaned up. The side, and what it is on, are different aspects being mixed up here.
