Train Speed in India to increase by 200km per hour with the support of Russian Railways, according to a reports by the Economics Times(ET). The fastest train in India is currently is Gatimaan Express with top speed of 160 km per hour.
The collaboration is on a 575-km stretch between Nagpur and Secunderabad. Part of the proposed techniques to reach this desired limit includes reconstruction of railway alignment as well as treating the earth bed where there are speed restrictions as well as a new type of passenger cars with coaches.
A high-speed rail network will also require safety measures for pedestrians and motor vehicles at rail crossings. Keeping this in mind, overpasses, anti-collision and anti-ram barriers as well as automatic alarm systems have been suggested.
It has, however, expressed concern over "a number of large bridges with speed limits" on this particular stretch and has recommended a detailed survey of all these structures on the basis of which measures for reconstruction/repair will be taken up.
It has also been pointed out that railroad switches, which enables trains to shift from one track to another, at stations on this stretch are not suitable for a speed of 200 km per hour and a different type of switch has been recommended.
A digital technological communication network for the entire section, instead of the existing radio communication, was also proposed.
