Sorry in advance, this mail just rehases arguments that I made before,
but it seemed polite to reply.

That's precisely it, point A and B continue to exist, they can be
mapped as abandoned/disused. What's between A and B did not continue
to exist, and should not be mapped. We know perfectly where New York's
World Trade Center used to be but there's no tower=dismantled at that

And unsurprisingly, I argue for A. Because it reflects the current
state of the railroad.

I do understant the appeal of being able to create a relation where
each member follow the previous one without holes. But if reality has
holes, so should the relation.
