Yeah some overnight trains can adjust their gauge on the France/Spain border.
On the China/Mongolia border on the other hand they disassemble the train, lift the train cars up one by one (with passengers inside), switch out the boogies and then reassemble. 3 hour process, you can fully sleep through it and not notice.
