this list a number of what a mapper would call an object (bridge, tunnel,
cutting)
but a render associates with another object to render it correctly and thus
calls it a property.
these are properties, because they are added to an object to detail its
position (on a bridge, in a tunnel or cutting), they do not map the bridge,
tunnel or cutting itself, just referring it indirectly.
Using that logic
a parking area is a property of a parking aisle.
a fuel station is a property of a driveway.
and so on.
Bridges, tunnel and cuttings are physical objects that have their own
properties (names, heights, widths, materials etc)
that can be independent of whatever else they may be related to.
A single bridge may carry a roadway, rail lines, water pipes, gas pipes and
electrical supply lines.
I would not view the bridge as a property of any of those things but as an
entity itself.
