Running faster 160kmphand above on the present Indian tracks say NDLS-KOTA-BRC-BCT is basically impractical today because
(1) the track is super saturated saturated, and few 160kmph trains on the route shall badly affect the running of other trains SF/Passenger/Freight.
(2) Due to a large number of curves (whopping 495 as reported i.i. one curve every 2.7km), the train shall hardly touch its top speed for much less than 50% of its run

Higher speed operation shall entail frequent acceleration, deceleration of the HST and much wear and tear to track as well as train bogies. It is not good for safe operation of train. Also much improvement in journey time and avg speed will not be possible.
Track alignment of majority of IR routes was fixed over a century ago, when speed (160kmph+) of operations was not an important consideration.
Best option is to go for straighter track alignment for the large scale tripling of main lines going on and planned for future. A few 160kmph+ trains that are planned on the route can be operated on this straight track so that top speed is achieved for almost all the time during the run, and a non stop train may give an avg speed of around 120-130kmph between the destinations. The straighter track shall permit further upgradation of speed to say 200 kmph or more in future.
Other option is to upgrade the tracks in a span of about 3 years and by that time DFC shall be ready to take on all the freight trains of the route.That will be right time to operate 160kmph train without straining the network and disturbing the existing traffic, rather than making hurry when IR is financially much stressed.

Are public money for wasting ?
If they are putting cart before horse, how can whole country run...
"Mr Prasad has said that to run high-speed trains, signalling needs to be upgraded. There are 495 speed-killing curves on the tracks between the Mumbai and Delhi section."
If signalling is not upgraded the High-speed trains are dangerous....

Buying Trains before Signalling is upgraded ...
Is this govt wise or what ?
