Thiruvananthapuram – Kasaragod

Semi High-Speed Rail Project


line oif silverline

Kerala even though known to be a linear state with a population of only 3.45 crores is commonly divided and called Southern Kerala, Central Kerala, and Northern Kerala. The Highways are choked with the rush of vehicles and the existence of residential and commercial establishments along the major highways makes the road development a dream which will not happen in the near future. With road development at standstill, new vehicles are entering the roads of Kerala at the rate of 1 million per year.

Considering the capacity of traffic served by the rail corridor and the comparatively less quantity of resources required for realizing rail projects, a rail corridor connecting the North and south ends of Kerala seems to be ideal for the state.

Since the existing rail corridor is serving the trains to travel at a low speed of 45km/hour only, the Government of Kerala in association with the Ministry of Railways have decided to construct a Semi high-speed rail corridor of 529.45 km length from Thiruvanathapuram to Kasargode which will take only 4 hours to travel between the two cities by traversing at a dream speed of 200 km/h. This project is known to be “SilverLine”.

The 529.45 km SilverLine corridor connecting Kasaragod and Thiruvananthapuram, with an operating speed of 200kmph, eases the transport between North and South ends of the state and reduces the total travel time to less than 4 hours, compared with the present 10 to 12 hours. The intermediate stations include Kollam, Chengannur, Kottayam, Ernakulam, Kochi Airport, Thrissur, Tirur, Kozhikode and Kannur.

SilverLine will bring remarkable changes in local commute, by improving the travel time and quality of transportation. Every kilometre travelled by a person on semi high-speed rail is a kilometre not travelled in an automobile. There will be a substantial reduction in road accidents due to decongestion on roads. SilverLine also provides last mile connectivity which will transform people’s perception towards public transportation.
