Big cities with nothing in-between is a good sell for HSR. Europe's two largest countries that have that population distribution pattern (France, Spain) rely heavily on very fast HSR (300-350km/h). The countries with more distributed, but also more dense population (UK, Germany) rely more on fast networks with more stops, but less maximum speed (200-250km/h).
