In the case of Edgeware Road they are really different stations, serving different lines, no underground passage and a really busy road in between. It's a bit same for the three named West Hampstead. > > AFAIK, the idea was as follows: > > > > station > > ======= > > > > The whole area with buildings and platforms: > > - area: > > - railway=station > > - area=yes > > > > - alt_name=Edgeware Road > > - name=Edgware Road (Bakerloo) > > - or: > > - name=Hampstead Heath > > > > - network=London Overground > > - naptan:ActoCode=9f8798 > > ... > > > This looks good and seems ideal, tho is not quite per the wiki.. i > think the wiki still prefers a single node tagged as a > railway:"station" for the benefit of placing the name correctly ( and > maybe for the simplification of all stations having a single Node ? > maybe maybe not ) I don't tag for the renderer... > > station's building > > ================== > > > > - area: > > - building=station > > or > > > > If there is no station area or building: > > > > - node: > > - railway=station > > - all the tags from "station" > > > > This looks good too, tho not what's folowed, many single buildings are > tagged as an entire railway=station with no area for stations it seems It's sometimes difficult to see/know if an area makes sense. For most tube stations (like the one in Kilburn) the area is exactly the station building, having an extra area then makes little sense... > > > platforms > > ========= > > > > way (or area): railway=platform, ref=<nr> > > > > Where the train stops: > > > > - railway=halt (on the railway track itself as a node) > > - name=Kilburn Park > > - line=Bakerloo > > - network=London Underground > > looks great .. tho still not quite sure of the difference between a > "halt" and a "stop" a "stop_position" etc.. mostly seem to be used > interchangeably and in reality interchangeably with a "platform" etc.. well, platform is the physical platform. A train can't be one one (but pedestrians can). Whether it's halt, stop or stop_position I don't know. To be fair, I don't think "halt" is the best choice. > > station entrances > > ================= > > > > - station building entrance: building=entrance > > - tube: railway=subway_entrance, name="Exit <nr>", ref=<nr> > > This looks great.. but in most (/all) cases i have looked not > followed; instead if there are multiple exits each is wrongly tagged > as a station, and as often there is no single station visible in the > real world (its all underground) there is then no single node for the > station.
