Wireless Pole - The Vintage Technology

Hello Readers ,

This is my next post in the continuation of my beloved reasearch about my beloved hometown.

Let me give you a quick recap from my last post that when bishop cotton school was suppose to use Jutogh town for his purposes however due to conflicts of the paper work was not able to . So British army started using it to utilize this place more. As a result a huge magnificent structure came into existence by the name of Wireless pole.



This Pole is one of the amazing structures i have seen in my life.This is a goliath of iron metal of aprox 80 Ft. ( i might be wrong ;)  Through my childhood i have heard its name as wireless poll . But now has the time came to quench our thirst for the question why it is called Wireless pole.

i am not sure about the dates when this pole came into existence. However in my upcoming trip to this town will gather more facts on this.

The reason is pole was meant to use a communication tool .Which was used by the British army to communicate .

The Technology which British army used was heliograph telegraphic signals.Wireless solar telegraph that signals by flashes of sunlight (generally using Morse code) reflected by a mirror. The flashes are produced by momentarily pivoting the mirror, or by interrupting the beam with a shutter.The heliograph was a simple but effective instrument for instantaneous optical communication over long distances during the late 19th and early 20th century. Its main uses were military, survey and forest protection work. Heliographs were standard issue in the British and Australian armies until the 1960s, and were used by the Pakistani army as late as 1975.

Signal mirrors are still included in survival kits for emergency signaling tosearch and rescue aircraft.

The same wireless poles were built in Dagshai cantt as well.

The Image slide show i am going to include in this post will show you some more panels and objects with Visual explanation of Wireless pole .

Rebel in the hill : Unsung Hero of past from Jutogh

T HE  first war of India’s independence in 1857 by the Indian soldiers of the British army was not limited to Meerut, Delhi or big cities . It was documented throughout the pages of history that  The events of patriotism at Kasauli and Jutogh in Simla Hills had made some of the hill chieftains to rise against the British and help the mutineers. They were very few in number. But their heroic deeds put fuel to the fire. This was the time when the danger of revolt emanated from Lahore, Jullunder and Peshawar as well. At most of these places Hindustani regiments known as Nussree Battalions were posted. It was at Kasauli that a group of native sepoys had looted the government treasury and fled to Jutogh under the leadership of Subedar Bhim Singh. A police chowky was also burnt. Their aim was to attack the British officers and families at Simla. This operation could have been suc cessful but for the treacherous behaviour of his fellows who had leaked the plan to authorities.

Jutogh Rail Way Station Jutogh: Located just 8 km away from the city centre, this army cantonment is near Totu, an important suburb of Shimla city. History Shimla (then spelt Simla) was settled by the British shortly after the first Anglo-Gurka war,   and is located at 7,116 feet (2,169 m) in the foothills of the Himalayas. By the 1830s, Shimla had already developed as a major base for the British.    It became the summer capital of British India in 1864, and was also the headquarters of the British army in India. Prior to construction of the railway communication with the outside world was via village cart. The railway was constructed on a two foot gauge (610mm) by the Delhi-Ambala-Kalka Railway Company commencing in 1898.   The estimated cost of Rs 86,78,500, however, the cost doubled during execution of the project.    The 96.54 km (59.99 mi) line was opened for traffic November 9, 1903.    Because of the high capital and maintenance cost, coupled with peculiar worki

My recent visit to Jutogh & i clicked few more pics . Tried to revisit the history ,gathered few more facts.
