I recently found some nodes in my city that are part of an abondoned railtrack and I wonder why they would make their way into CS, because there is no street/road/track whatsoever.
They are part of a longer way, which has a name, but is not tagged as highway. So they should not be fetched by the query. The whole way has many more nodes, that do not show up in CS. So why do these four do? The way itself was changed in OSM a month ago (after the last update from OSM to CS), but these nodes where not part of that change. Only the location of other nodes were changed.
Anyone an idea, why they are here?
