I recently travelled on an old Nightjet, and oh yes, they're due an overhaul (ventilation broken, no airconditioning present, uncomfortable to sit).
But looking at the new design, I'm not convinced: You're still sitting with your back against a vertical wall. I cannot sit that way. Hoped for a comfortable backrest that can be folded away for sleeping. And a longer table, so all occupants can have breakfast or use laptops
It does have surveillance cameras, though...
