NEW DELHI (AP) — Prime Minister Narendra Modi on Friday inaugurated one of the most ambitious railway projects ever built in India, which will connect the Kashmir Valley to the vast Indian plains by train for the first time. Dubbed by government-operated Indian Railways as one of the most challenging tracks in the world, the 272-kilometer (169-mile) line begins in the garrison city of Udhampur in Jammu region and runs through Indian-controlled Kashmir’s main city of Srinagar. The line ends in Baramulla, a town near the highly militarized Line of Control dividing the Himalayan region between India and Pakistan.
