Mumbai: The Railways is upbeat about running high-speed trains like the Spanish Talgo and Rajdhani between Mumbai and Delhi at a speed of 160 kilometres per hour (kmph), but Chandrika Prasad, a former Railway Board member, has warned of pitfalls for running trains at high speed (160-200kmph) on the Mumbai-Delhi section. In the latest issue of a railway industry magazine, 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.
Sources also said that Mr Prasad has given suggestions on upgraded signalling to the railway ministry. However, when contacted, Mr Prasad refused to comment on the issue and said, “I have highlighted it in

the article. We need to upgrade on the lines of other foreign countries like US, China and European countries who had upgraded their lines before going with running high-speed trains.”
However, Mukul Jain, divisional railway manager, Western Railway, said, “The Railway board has asked to work out on signal upgradation plan for running high-speed trains at 160kmph and we are in the process of preparing the plan.”
Mr Prasad has stated in the article that while driving a train at 180-kmph, the train driver will encounter a signal for less than a minute’s interval. “In addition there are issues relating to speed limits on curves, permanent restriction and temporary speed restrictions. Imagine the tremendous strain on the driver’s mind while running his train at such high speed on the Mumbai-Delhi section.”
He points out that signalling modifications should be carried out to provide timely warning for closing of the gates and to road users. The current Indian Railways signal manual does not lay any guidelines on signalling for running high-speed trains.

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
(3)

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.
