World's highest railway line coming in India
India is adding the world's highest railway line to its infrastructure.
India Railways this week started the location survey for the 498-kilometre long Bilaspur-Manali-Leh track, along the China border.
The track will be at an altitude of 3300 metres, meaning it will overtake China's Qinghai-Tibet line as the world's hight railway, reports the International Business Times.
The all-weather track is one of the four important railway lines along the China border identified by India's defence ministry.
* Best train trips: 10 of the greatest rail journeys in the world
* The world's highest bridge opens for traffic in China
* Amazing footage of highest suspension bridge in the world
* Peek inside New Zealand's longest road tunnel
Once completed, the line will enable India to ferry troops and equipment more easily to the border.
Railways minister Suresh Prabu said the project was estimated to cost 157.7 million rupes (NZ$3.36m) and would be funded by India's Ministry of Defence.
The location survey is being carried by government engineering company RITES.
"RITES has deployed its expert team to carry out this challenging task. The survey will be carried out in three phases and is slated to be completed by 2019," said a Railway Ministry spokesperson.
The rail line is expected to improve access to the remote area, which at this stage is accessible only by a road route that is open five months a year.
