I think that it's quite hard for data consumers (again: think of an overpass-query to find all mid-stations) to determine which role a station has. Like Martin said: Why not just solve the (huge!) special case of mountain aerialways where we really have one bottom_station, zero or more mid_station and one upper_station?

So what is wrong with ele=* on the stations and the topography of the line? Completely (for OSM purposes) objective and uncontroversial. The data consumer/renderer can make their own mind up about nomenclature. Many of these lifts go up to go down, or go down to go up, as they cross ridges and valleys. One man's incline on a segment of the route is another man's decline based on the station altitudes. Let's tag the facts, and not subjective naming.

Alexey, you're right, anyway physical properties like incline are better tagged on way than on relations.


and horizontal aerialways aren't completely unheard of either. The incline solution works only for a subset of aerialways. Generally, for horizontal aerialways top and bottom / valley do not apply, i.e. the original question is directly related to a specific (frequent) configuration: an aerialway which surmounts a significant height difference. We do not have to find a universal solution if the question relates only to this special case.
