Well I guess you could narrow it down to just H and A, convert B to room for two more crew rooms. I don't think you all realize how much room I plan for the Conductors office though. I think they should have a work space where all the tickets (sorted by destination) can easily be laid out, room for delay reports, train orders, manifest, and of course you can't forget the grip. The space could function for both Conductors if large enough.
Why would not just one bedroom be enough room?
Replace the lower bunk/bed with a desk and chair, and the Conductor would pull down and sleep in the upper bed/bunk. I mean, it is not like the Conductor needs to sleep and work at the same time (though Amtrak might claim otherwise).
If there are two Conductors, then each gets a bedroom. leaving the third's space for a lounge/snack area (as previously suggested).
BTW, the Viewliners already have a linen closet.
