station=subway can (or better: should) also be applied to stations which are above ground but where subways services stops. Many such networks have long sections above ground because they are easier and cheaper to build and maintain. station=* can be used by map style authors to distinguish between usually more important stations of trains (those operated by the national railway company or its successors). > * Why is railway=halt a main tag instead of 'railway=station, > station=halt'. To me a halt is a subtype of station, similar to > 'station=subway'. Ask those who invented it long ago. Use railway=halt for "stations" with very few infrastructure (just platforms, small shelters, no shops) and railway=station for the others. German and Austrian mappers use railway=station/halt differently. Their criteria to distinguish the two ones is the presence of points (except subways where everything is tagged railway=station except subways which are indeed light rails or underground trams). > * Stop Area relations - What are they for?

Some mappers tend to fill them up with a large pile of other stuff (benches, footways, waste baskets, vending machines, …). I think that they should stay small and manageable. There are map styles rendering some stop area like areas. Thunderforest Transport (aka OpenTransportMap) is one of them. I don't know the secret sauce behind it but another (not public) map style I know uses a simple "GROUP BY name" to create such areas. I am not sure whether OsmAnd supports them or if it also only groups by name and other tags but Osm2gpsql which is used by many map style authors doesn't.
