What is the other name of the 'Siliguri Corridor' situated in Northeast India?

The 60-kilometres (37 miles) long and 22-kilometres (14 miles) wide Siliguri Corridor in the Indian state of West Bengal is also known as the “Chicken's Neck”. It connects India's north-eastern states with the rest of the country through the city of Siliguri in the Indian State of West Bengal. The countries of Nepal and Bangladesh lie on each side of the corridor and the Kingdom of Bhutan lies at the northern end of the corridor. The Indian state of Sikkim also lies at the north of the corridor.

It is a sensitive area surrounded by three countries. The strip is heavily patrolled by the Indian Army, the Assam Rifles, the Border Security Force, and the West Bengal Police. All land transportation between mainland India and its far northeastern states uses this circuitous corridor, as there is no free-trade agreement between Bangladesh and India. The route has a major broad gauge railway line. Electrification of this double-track corridor is in progress with assistance from Central Organization for Railway Electrification (CORE).
