Power lines should have a default layer=5, and so no bot should ever
join them to anything.

But you're right about railways -- not clear if it's overgrade, below
grade, or an at grade crossing.

Other than from data imports, the only way to get a duplicate point is
for an editor to create one, so perhaps the long-term fix is for
editors to move a node slightly when they are asked to split a node
(in JOSM, Un-glue Ways).
