* Will you consider premium trains only to be a factor of speed upgradation? Why are then, other non premium superfast trains along NCR upgraded to 130? MAS-BZA serves huge traffic from Delhi-Chennai line, Howrah-Chennai line. Hence, the traffic is not just from these areas only, but also from adjoining regions like Northeast in case of Howrah and Northern & Western India in case of Delhi-Chennai line? While introducing surge pricing in premium trains, Railways confessed that premium trains carry 0.6 % passengers. I find it hard to believe that policies of speed upgradation are framed by keeping that 0.6% passenger share in the mind.
* Can you provide source that claims BZA-MAS is 130 kmph certified? And by the logic of...
more... premium trains, MAS-SBC section has decent number of premium trains to invest in. Still nothing for last 20 years.
* 15 years time is too much to give an excuse of track geometry. And at the end, you are proving my point, that while other routes that carry significant passenger segment are still lingering around speed of 100 or 110, some are upgraded to even higher. LHB technology is in place for around a decade or so. Rake conversion and line upgradation can allow 130 kmph speed in central/south India as well. Similar thing has been possible along Delhi-HWH chord line just because everything was in place. But now we have LHB trains along South India, more are coming; but we do not have infrastructure to run them at MPS, just like there are no intentions to do so.
At the end when, a particular part has been ignored, ignoring it further wont create harm because focusing on one area is enough to generate required media hype and applause.
