How do they avoid “clack-clack” sounds on high-speed trains? Are the rails made without gaps? And how do they manage thermal expansion then?

Maglev, is a system of train transportation that uses two sets of electromagnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction. Such trains rise approximately 10 centimetres off the track.

CWR has no or very few joints. To work with the expansion/contraction they take out rail in the summer and add it back in during the winter. Stick rail has more movement and doesn’t require as much adding or removing rail.

Why is everyone focused on the rails, when it is clearly not the rails who make the sound?
OP, the clak clak sound comes from “flat spots” (direct translation from german) on the wheel that happen when high speed trains have to initiate a high power break. On regular track and in most situations, the wheels have anti blocking features, like a car does.
Sometimes these fail, or the track conditions make the wheel simply glide over it, thus scraping flats into it. Sometimes the material is pushed onto other parts of the wheel, and it makes the sound even louder. If the train keeps going now what you hear is the typical clak clak sound.
