Travel time by train is mostly about how many stops [edit: legs] you need (which add through wait times) and what part of the network you're on: Brussels/Cologne, which is used on the London/Cologne route was only usable up to 60km/h or so 7 years ago. That part took nearly as long back then as the entire LON/CGN trip does now.

Paris - Stuttgart - Nuremberg (580km) takes 6h51 including one hour between connections in Stuttgart.

Berlin - Stuttgart (591km) has a 5h34 direct connection.

Frankfurt - Bern - Milano (~700km) takes 7h47 including 30 minutes in Bern

OTOH, Frankfurt - Cologne (for which a dedicated high speed rail route was built nearly 20 years ago) is about 200km in 1h04.

What about the terrain? If it were possible to go from sf to la without the elevation changes, they would have made the road by that route.

Terrain also plays a part. Frankfurt-Milano crosses the Alps, and it's slower (per distance) than the other examples.

The wait times are not the big problem - the problem is the time needed to decelerate and accelerate the train at each stop. E.g. a freight train of 1.200 tons needs 1km from 100 km/h to 0, and a high-speed passenger train, e.g. ICE 3, needs 3.3km from 330 km/h to 0.

Sorry, I picked the wrong term. Not "stop", but "leg".
