Hmm. Googling "Pacific Charters" doesn't show anything.
I found "Pullman Rail Journeys":

The Luxury Train Club is offering the A – Class Master Bedrooms with private facilities – drawing room, shower, toilet and wash basin, at fares starting from USD $2,850.
Another outfit (Viator) offers a bedroom for $2500. That's pricey, I'd say. Especially when you're going to spend ⅓ of the trip in darkness or asleep. It would be nice on a different train, perhaps, but not CONO. At least not for me.
The Management frequently doesn't have a great appetite, so that might be a wasted luxury. Amtrak will be just fine for us!
I asked Rion about the horns and that's what he said. He mentioned that they tried to cut back on the horns, but there was a big jump in human vs train incidents.
Any idea why the consist is flipped in the winter?
