There is something wonderfully unhurried about a train that takes its time getting to the mountains. It rounds bends that seem drawn into the hillsides, slips through tunnels, crosses bridges suspended above valleys, and pauses at stations where the air smells of pine needles, damp earth, or freshly brewed tea. India's heritage toy trains offer precisely this kind of travel. The Darjeeling Himalayan Railway winds through the tea-growing slopes of West Bengal, the Kalka–Shimla Railway climbs into the cedar and pine forests of Himachal Pradesh, and the Nilgiri Mountain Railway traverses the green highlands of Tamil Nadu. Together, they form the UNESCO-listed Mountain Railways of India, celebrated for the engineering ingenuity that made these mountain journeys possible.
