It was constructed primarily during the British imperial days in India with an intention for rail road connectivity from the summer capital of British India i.e Shimla. This meter gauge rail network traversing the steepest ascending path in altitude measuring in 96 kilometers long and actually crossing over 800 bridges and viaducts have limited place in The Guinness Book of World Records for this accomplishment stated amongst the all hill railways listed to being one of the most picturesque rides ever made.
The Kalka Shimla Railway is a working rail link constructed in the mid-19th century with single-line narrow gauge and steep gradient, designed to connect to a highland town (simla) in height 7000-8000 ft (final height: 2211.98 m). With its geographical framing it correlates and simultaneously focuses on both scientific, and engineering, accomplishments with specific attention to colonialist and racial dispositions toward the hill peoples in the framing of railway technology.
