Yes please, pictures to add to a trip report are always welcome. And I actually have no clue how overnight trains in Sweden are!
May I ask how much you paid for a ticket? Booked a private compartment or a berth in a shared compartment? I'm interested to hear as well how the deal is with a hotel breakfast at the Radisson Blu included. Combined with a cosy train, sounds like good oldfashioned slow travel at its best!
