Hi It seems that the only problem with PTv2 that remains is the rendering of public_transport=platform, i.e. whether public_transport=platform (and maybe public_transport=station too) should get the transport mode tag(s) (bus=yes/tram=yes/...).
Note that the PTv2 proposal suggested to map the *stop position* 'as an icon depending of the vehicle type that is stopping at the position',[1] which may have led to some people mapping only stop_position's, others mapping only platform's and still others mapping stop_position's and platform's which in turn has led to complication and confusion. [1]: https://wiki.openstreetmap.org/wiki/Proposed_features/Public_Transport_v3 As this question pops up every now and then, it might make sense to finish discussing this. I'm double posting this message on the transport mailing list, so that the discussion can continue there.
