That is the problem with high speed train connections. Add too many stations and the travel time will go up quickly. I see it here too. High speed train between Amsterdam and Brussels (IIRC). Some cities where it passed demanded it stopped there too. But it kinda defeats the purpose. High speed trains need to operate like airplanes which travel distances over 300km. Otherwise a car or regular trains are usually quicker.

A high speed train taking the scenic route seems more a basis for a comedy sketch than a civil engineering project.

China have a similar problem too, but there is a solution: HSR stations that can be passed at speed. When a CRH train passes a station, it just speeds through at 350-380kph. The running lines never have a platform next to it, except at major stations where all trains must stop at anyway. China Railways also engineered high speed switches that can tolerate 400-450kph straight and 250kph side for use in those passable stations.

I was once on a platform waiting for another train when a train speeds through at 350kph on the second line from the platform. It is loud and a bit scary to be honest.

In some places those platform track/non-platform track arrangements are used as passing places. They time the slower train to be at the platform as a faster train passes straight through and overtakes.

On the Shanghai Maglev the two trains pass each other at 430kmh, it's as scary as you think it is.
