How strong are those rails laid by those big Chinese machines?

Question

Saw i saw clips of this machine laying concrete down on gravel and rocks and rails for the trains https://vm.tiktok.com/ZS8mnMfM8/ .

But those concrete bars don’t seem to be anchored to anything so how strong are they actually?

I assume they’re going to come through in a later stage— maybe even a unit on this same apparatus, just out of frame— and dump a bunch more ballast (gravel) in between them. That’s what they do with wooden railroad ties, and those do a fine job anchoring rails on traditional railways.
