Nilgiri Mountain Railway
The Madras Railway initially operated Nilgiri Mountain Railway built by the British in 1908, in Tamil Nadu.
This railway still relies on steam locomotives and it comes under the jurisdiction of the newly formed Salem Division.
In the year 2005, UNESCO added the Railway as an extension to the World Heritage Site of Darjeeling Himalayan Railway, and thus the site is then came to be known as “Mountain Railways of India.”
For the past several years diesel locomotives have taken over from steam on the section between Coonoor and Ooty. Local people and tourists have led a demand for steam locomotives to haul this section
The ‘Nilgiri Passenger’ train covers a distance of 26 km and travels through 208 curves, 16 tunnels, and across 250 bridges. The uphill journey takes around 4.8 hours, and the downhill journey takes 3.6 hours. It has the steepest track in Asia with a maximum gradient of 8.33%.
