the rail and road share an intersection. it is a level crossing. The whole
point of a level crossing is to say “Hey!” the road and train meet here! that’s
why they share the node.
a train in a tunnel doesn’t - so it doesn’t share a node with the road(s)
above. There is no notice to a driver of subway lines, storm drains, water
pipes, etc in the road as you drive - why is the culvert a node property of the
road?
Water and a road sharing the same node on the same level is called a ford.
A culvert is a type of tunnel. Zoom in and make a tiny going across the road
and tag it as a culvert.
In general, Tunnels are a property of ways, not nodes.
Occasionally it is not completely sealed (there is a grate, or just rail ties
and track), but it none the less has no bearing on the traffic on the track,
road, or path above it - so it does not share a node with the road/track above
- just as power lines crossing above do not either.
It is not a stream that you have to get your car through.
it is a small tunnel under the road.
So tag it as a way. tunnels on nodes - especially on shared nodes with roads
that are not in tunnels seems really really bad.
