Darjeeling Himalayan Railway

Lonely Planet review

The Darjeeling Himalayan Railway, known affectionately as the Toy Train, made its first journey along its precipice-topping, 2ft-wide tracks in September 1881 and is one of the few hill railways still operating in India. It's even listed as a World Heritage site. Besides its regular diesel service to/from New Jalpaiguri and steam service to/from Kurseong, there are joy rides during high season that leave Darjeeling at 10:00 and 12:50 for a two-hour steam-powered return trip to Ghoom.
