I’m not fussed with top speeds. Average travel speed that takes into account waiting for the next departure is a more practical measure. A high speed train that stops in every town has a lower effective speed than the top speed suggests. A high speed train with hourly departures instead of every 30 or 15 min means you wait more. And of course high speed means higher cost. The average person is very price sensitive on transportation costs.
