New Kazakh trains. Designed by Spaniards, assembled in Kazakhstan. Noticeably faster and more comfortable than their predecessors. For some reason, locals really pay attention to the fact that the doors are automatic, and if you're late, the train won't wait for you.

If you're lucky, you can snag a spot in a half-compartment: there are only 2 seats (lower and upper). But there's only one of these half-compartments per car.

Inside the car everything is good, but the designers clearly didn't try to sleep there: an insanely bright blue LED indicator light on the switch (one by each bunk) blinds you and keeps you awake.

But the railway website is just terrible. I managed to buy a ticket on the third try.
