When you think of Amtrak, luxury travel is probably not the first thing that comes to mind. But in an attempt to increase ridership, Amtrak has joined forces with GrandLuxe Rail Journeys, formerly known as the American Orient Express, to offer luxury passenger rail service aboard vintage Pullman cars. The luxury cars will be attached to the back of Amtrak’s regular trains, but will be treated as separate — no mixing with the passengers from the other cars. Among other amenities, the sleeping cars will be equipped with a lounge featuring a live pianist and a dining car offering five-course meals.
