platform=stop_position is a node that is part of the way. As far as I'm
concerned, they are not super important. What you call stop position (the
sign) in the above paragraph seems to be what corresponds to
highway=bus_stop, if it were a bus stop. That's the node, detached from the
way that I would map as railway=tram_stop for representing the stop in the
route relations, with all its details.. Of course, when you only have
aerial imagery, it may be difficult to know that exact position. If there
is a shelter I would put this node near to it, if there is nothing, I would
place that node somewhere in the middle of a typical tram's length.

If there is only a sidewalk, we would be done. If there is an actual
platform, I would add a way or a closed_way with railway=platform, and
possibly its height, tactile_paving and wheelchair. No name, no other
details, they are on the node that represents the stop.

If there is a shelter, I would map it with a closed_way; amenity=shelter,
shelter_type=public_transport.
