Kalka Shimla Railway Line
On 9 November 1903 the narrow gauge Kalka Shimla Railway Line opened to traffic. Initially, there were 107 tunnels and in 1930. as some of them were defunct, they were renumbered to 103. Today, there are a 102 but for tradition's sake, the line is still referred to have a 103. There are eight hundred bridges and nine hundred curves and during course through the picturesque countryside, at times the line goes through a succession of reverse curves of over thirty.
On 7 July 2008, UNESCO's World Heritage Committee gave the Kalka Shimla Line World Heritage status saying:"The Kalka Shimla Railway represents an exceptional technical achievement in the development of the Himalayan mountains because of its length, its altitude and the difficulty of the terrain through which it runs in difficult tropical climactic conditions." While H.S. Harington was the Engineer, the Kalka Shimla Railway Line is supposed to have been built on the trace 'revealed' by Bhalku, a labourer who worked on the line. Acknowledging the latter's role, the railway museum at Shimla is named the 'Baba Bhalku Museum".
The views all through are magnificent and the steady journey allows one to soak them well. There are fields, open valleys and woods that the train passes through- apart from the bridges that resemble Roman aqueducts and the numerous tunnels.
