... that this poll resulted form http://bangalore.praja.in/blog/murali772/2009/01/25/drms-presentation-regarding-commuter-rail-etc

Since there may not be data to back up the answer on economic viability, this question should be reprashed "Do you FEEL you need a 300+KMPH service which is more comfortable and can connect cities in Karnataka faster than currently done by IR, assuming it doesnt cost more than any other service to provision this?" Let us express need and then look at ways of making it happen cost effectively

Secondly, if this poll is a meant to be a conclusion to this thread then we are sadly missing a lot of other points made in my post there. Let us go back to the thread and visualize the scenario I have painted there. What it means to Bangalore, its transportation plan. Does this give us a perspective of the alternatives involved and show us the imperative of what and how much we need from IR. How does it link to how our transport should look in 2020.

How about we have a round of all of us here writing just the vision - how do we want the transportation scene to be? Write only the "what" aspect, just leave the how to get there part out. No ideologies, privatization socialism etc, just our vision for how we want to get from bangalore city to yeswantpur, nellamangala, tumkur, or hassan - basically cover local, suburban and itra city transportaion vision for the state.

Well, everyone wants to travel faster. Who doesn't wish not to travel on an ICE or Eurostar or Maglev trains within Karnataka or within India. But, there are lot of other things which have to be addressed first by Railways. Once these things are addressed which are residing as it is from decades, then high speed rails can also be explored.

Leasing out tracks to private party will not work out, it is not the rolling stock that we are lacking, it is the track infrastructure. For instance the rolling stock running for the Shatabdi Mysore is capable of 150 kph. The WDP4 engine used runs at 150 kph in Konkan Railway, but, it is unable to run at such high speeds in Bangalore-Mysore / Bangalore - Tumkur routes. We need new track infrastructure to serve the high speed rail. 

I mean to say we are still not getting what IR is capable of serving and what it is serving to other states.

If  high speed rail is a PPP model without Government funding, let the infrastructure build and run start now itself. When so much rail infrastructure is lagging within Karnataka, we cannot have the Government invest so much on the high speed rail on its own.

Even advanced countries like the US are still lagging in High Speed Rail infrastructure. Companies will not be ready to make such huge investments where returns are not guaranteed.

Starting Airports all over Karnataka and running flights would be more viable who want high speed travel within Karnataka.

300 kph speed rail itself is not enough to answer this poll. Train is a tool, whats more important are the usage scenarios, or the so called "use cases". If you are talking High Speed from MG Road to the airport, with usage restricted to air travellers, then the answer perhaps is no - not feasible. But if we are talking High Speed from Bangalore to Shimoga, Bellary, Hassan or Mysore, I would say yes. It should be possible to make Mass transport based connectivity economically feasible in our densely populated country.

Now, the other question is about the cost of 300 kph technology? Why 300 kph, will going down to 200 kph still keep it useful and increase feasibility.

Anyway, I voted yes.
