Tunnel at Kalka–Shimla, Himachal Pradesh



Tunnel at Kalka–Shimla, Himachal Pradesh, India

* The Kalka–Shimla Railway is a 2 ft 6 in (762 mm) narrow gauge railway in North-West India travelling along a mostly mountainous route from Kalka to Shimla.
* It is known for breathtaking views of the hills and surrounding villages.

... * Shimla (then spelt Simla) was settled by the British shortly after the first Anglo-Gurkha war, and is located at 7,116 feet (2,169 m) in the foothills of the Himalayas.
* On this route a city named Solan is passed through, which is also known as mini Shimla.
* The Kalka–Shimla Railway was built to connect Shimla, the summer capital of India during the British Raj, with the Indian rail system.
* Now, Shimla is the capital city of Himachal Pradesh and Kalka is a town in the Panchkula district of Haryana.
* Spectacular scenery along the whole route, and the marvels of its construction, keeps the traveler on this line spell bound.
* On leaving Kalka, 656 meters (2,152 ft) above sea level, the railway enters the foothills and immediately commences its climb.
* The route offers a panoramic feast of the picturesque Himalayas from the Sivalik foot hills at Kalka to several important points such as Dharampur, Solan, Kandaghat, Taradevi, Barog, Salogra, Summerhill and Shimla at an altitude of 2,076 meters.
* Originally 107 tunnels were built on Kalka Shimla Railway Track. In 1930 they were renumbered and four of them were discarded so only 103 were left.
* In 2006 tunnel number 46 was dismantled so presently only 102 are in use.
* But tunnel number 103, the last tunnel in Shimla, is still famous as tunnel number 103 as this place has become a famous landmark of the town.
* The longest tunnel is at Barog, and is associated with local tales and legends.
* As per a famous story of Colonel Barog, the engineer of this tunnel, had committed suicide here. He started digging the tunnel from both ends and could not align them.
* So he was fined 1 rupee. He could not stomach up that stigma so shot himself in the tunnel.
* The line has 864 bridges, one of which is a 18.29 metre (60 ft) plate girder span and steel truss. The others are viaducts with multi-arched galleries like the ancient Roman aqueducts.
* Bridge No. 493, historically known as the "Arch Gallery", situated between Kandaghat and Kanoh stations, is an arch bridge in three stages, constructed with stone masonry.
* Bridge No. 226; between Sonwara and Dharampur is an arch gallery bridge having 5 tier galleries of multiple spans, constructed with stone masonry and bridging a deep valley surrounded by high peaks.
* The railway has a ruling gradient of 1 in 33 or 3%. It has 919 curves, the sharpest being 48 degrees.
* Climbing from 656 meters (2,152 ft), the line terminates at an elevation of 2,076 meters (6,811 ft) at Shimla.
