The Darjeeling Himalayan Railway, also known as the "Toy Train", is a 2 ft (610 mm) narrow gauge railway that runs between New Jalpaiguri and Darjeeling in the Indian state of West Bengal, India. Built between 1879 and 1881, the railway is about 78 kilometres (48 mi) long. Its elevation level varies from about 100 metres (328 ft) at New Jalpaiguri to about 2,200 metres (7,218 ft) at Darjeeling. Four modern diesel locomotives handle most of the scheduled services; however the daily Kurseong-Darjeeling return service and the daily tourist trains from Darjeeling to Ghum (India's highest railway station) are handled by the vintage British-built B Class steam locomotive, DHR 778. The railway, along with the Nilgiri Mountain Railway and the Kalka-Shimla Railway, is listed as a Mountain Railways of India World Heritage Site. The headquarters of the railway is in the town of Kurseong. Operations between Siliguri and Kurseong have been temporarily suspended since 2010 following a Landslide at Tindharia.
