Welcome to the railML forum! I am looking forward to learn more about
your visualization application, because it relates to one of our first
railML 3 use cases: Schematic Track Plan (see [1]). So, if you are going
to attend the upcoming railML conference (14.11.2018) [2] and railML 3.1
Dissemination workshop (13.11.2018) [3] in Praha, we may discuss in detail.

That is correct.

NetElements are topology elements and thus independent from "railway
typical" tracks and lines. The <line> as well as the <track> is located
as NetEntity on the underlaying topology (NetElement).

Yes, this approach is possible. In this specific microscopic model, the
location of the <track> corresponds with the <netElement>.

You mean "ne_01" instead of "ne_a01", don't you?

Yes, this is correct :-)
I am not sure whether the buffer points have to be added as demarcating
points of TvdSections, too, but I am sure the interlocking coordinator
can answer this remaining question quite fast...
