Those few times I've taken a sleeper, both private (Europe) and shared (China) rooms, I haven't slept as if I were in my own bed but I got a decent enough amount of sleep to call it a a "night's rest." But, then, it's also not unusual that, jet-lag or not, I'll have trouble getting to sleep in a hotel especially first night or so of a trip. So I guess I sleep well enough on trains (and on lie-flat seats in planes).
