The Darjeeling Himalayan Railway, also known as the DHR or Toy Train, is a 2 ft (610 mm) narrow-gauge railway based on zig zag and loop-line technology which runs between New Jalpaiguri and Darjeeling in West Bengal.
Built between 1879 and 1881, with six zig-zags and five loops, the railway is about 88 km (55 mi) long. Its elevation varies from about 100 m (328 ft) at New Jalpaiguri to about 2,200 m (7,218 ft) at Darjeeling. Although four diesel locomotives handle most scheduled service, the daily tourist trains and steam-enthusiast specials are hauled by vintage British-built B-Class steam locomotives.
