It's not clear to me from the documentation that I can do that in a way that achieves what I want to do and is compatible with accepted usage. If you can tell me how to do that I'll be very happy. Let me be clear. I want to decompose a route into segments and then construct some sort of relation (ordinary, superroute or whatever) that assembles them in sequence. I want to do this because I have a route which traverses some ways twice. I want to do this because the same route has ways which are traversed twice (A, B, C, D) but the first time the stop at C is ignored (you can neither board nor alight there) and the second time the stop at C is usable (you can board or alight). I want to do this because although the route is circular, it is "hairy" (in the mathematical sense), it's not an "O" but an "O=". The same way is traversed twice in opposite directions: in a non-circular route that would be two variants of a route master but this is a circular route. Being able to decompose the route solves several problems. As a single route it is a real pain to edit because the tools don't fully support the same way appearing twice (maybe there's a JOSM plugin that does it better). I still have a gap on the route according to JOSM validator but I can't spot it. It doesn't show as a red dot in the edit relation table, I can't see it by scrolling through the list of ways and looking at them, when I go to the validator and try zooming to the problem nothing happens. It's in one of the ways that gets traversed twice and it's driving me crazy. I think that subroutes would make it a lot easier for me to zero in on the problem. As a single route it's impossible to figure out by simple inspection of the query tool: https://www.openstreetmap.org/relation/8592409#map=14/52.0860/-4.6644 You tell me where it goes in what sequence without delving deeply into the relation. I'll give you a hint: it starts and ends here: https://www.openstreetmap.org/node/3642998002 Want another hint? It doesn't just start and end there, it also stops there in the middle of its route. Without looking at the details of the relation, tell me where it goes next after that starting point. Being able to decompose it into segments would allow people to see a sequence of segments in order (such as via umap) and it would be obvious what the route is. Having segments would allow me to deal with the stop that is passed twice (in the same direction) but is only used once - it would appear on one segment but not the other. So I don't care if it's a superroute, a master relation (I'm not keen on that because this route has several variants so I'd end up with a master relation of variants that are themselves master relations of segments), or something else. I'd just like to be able to do it. -- Paul
