Batasia Loop

The Batasia Loop is a spiral railway created to lower the gradient of ascent of the Darjeeling Himalayan Railway in Darjeeling district of West Bengal, India. At this point, the track spirals around over itself through a tunnel and over a hilltop. It was commissioned in 1919.
It is 5 km from Darjeeling, below Ghum. There is also a memorial to the Gorkha soldiers of the Indian Army who sacrificed their lives after the Indian Independence in 1947.
