On a train to Voss from Bergen, while I was on a trip to Erlend’s cabin.
There was a dedicated zone for children to ‘lounge’ in (kids dont lounge do they?) The space had a little ladder and tunnel, a T.V with movies playing.
What did happen was that the kids there got a lot more rowdy than they might have if they just had to be around their seats, and thereby causing more annoyances to other travelers. *edit: I thought the space was cool..
