Asia: Maharajas’ Express
Travel between: Mumbai and Delhi
Not to be confused with The Darjeeling Limited (unless you're trying to start a convo about how much you enjoy Wes Anderson films), this 88-passenger bastion of five-star opulence first rolled out of the station in 2010. It takes passengers on an Indian adventure complete with amazing daily whistle-stop excursions like an elephant polo match, wild game drive through Ranthambore National Park, and a visit to the Taj Mahal.
You could get used to: The 24hr butler service, Rajah Club with leather chaises, backgammon, private bar, peacock feather-themed Mayur Mahal restaurant, Dish TV (hello, ESPN!), and cabins adorned with "with rich tapestry, semi-precious stones, and antiques".
Outside your window: In addition to the aforementioned Taj Mahal, plan on taking in the amazing Indian countryside and all its caves, forts, and palaces, as well as Jaipur (the "Pink City") and Udaipur (the "City of Lakes").
A ticket will set you back: $6,840 for 8 days/ 7 nights in a Deluxe cabin, the train's least expensive accommodation. The Presidential Suite'll run you a tight $23,700.
