The reality though is that high speed trains aren't nearly as fast as you'd think from the claims of 250-300 km/h top speeds. Particularly in Germany, 130kph average speed on a route is very good. Replacing a 100kph train with a 130kph train doesn't make an enormous difference. In order to get double the usual speed, you need to have totally dedicated tracks, end-to-end, and they haven't done that in most places. Having trains run more often makes a huge difference in convenience and also allows you to not worry too much about missing your train.

They have done that on a lot of routes in France.
