The romance of India’s long-distance rail journeys hits its peak on its most luxurious trains, inspired by the imperial carriages of maharajas. Think air-conditioned, WiFi-enabled suites with attached bathrooms, separate cars for restaurants and bars, a business centre and a spa. They take in some of the best sights that India has to offer, from tigers in Madhya Pradesh to palaces in Rajasthan. Take your pick from the five most expensive luxury trains in India: Golden Chariot, Deccan Odyssey, Palace on Wheels, Maharajas’ Express, and Mahaparinirvan Express.
