for the tracks it doesn't seem right to tag "highspeed" where it isn't
highspeed, although it might be disputable which speed merits the term
"highspeed", even the European guideline 96/48 names differents speeds,
ranging from 200km/h via 250km/h to more than 300km/h (and it is from
1996). Later it was put to at least 190km/h. (Btw. more than 200km/h was
already reached by trains in 1903 in experimental settings). Contrarily, it
is much more interesting to see which parts of a claimed highspeed
connection is actually not highspeed besides the train that runs (slowly)
over it ;-)

Highspeed implies technical safety measures (likely dependent on the
Country / Region, i.e. legal requirements) regarding signalling and
location determination (in Germany LZB), fenced off tracks, short blocks,
etc.
