Re: You must work for HS2
"Note what i said. No such "assumption". The business case doesn't contain any assumption on the topic of productivity, it contains a pretty comprehensive meta-analysis of the topic (even a meta-meta-analysis in some cases). That's not what we call an assumption, that's what we call science."
What utter crap. The "meta-analysis" might as well be metaphysics. HS2 is a ghastly unecessary boondoggle, promoted by those who benefit from it, and supported by utterly unfeasible numbers. As somebody who has managed a multi-billion pound investment programme, I know a shit business case when I see one. As somebody in the target market (West Mids to London business traveller) I can see no material benefit only vast cost. And even with the vast expense of HS2 the wankers who have planned this have decided on a Curzon Street terminus in Birmingham, which is totally unconnected to the city's existing transport infrastructure, it just happens to be an unsued patch of land, rather inconveniently sited. At Euston, you've got a very, very poor interchange for onward connections to the City, and a terminal building that's barely suitable for current levels of traffic. And for onward travel, they haven't even thought the obvious of taking it into St Pancras to make a proper high speed route interchange.
If the incompetent turds at the Department for Transport wish to upgrade the network to meet this incredible growth in capacity, then all they need to do is (a) convert the existing first class carriages to second, and (b) lengthen the Pendolinos by two carriages. There's a few platforms need lengthening, but those changes alone would increase the seating capacity of each train by around 50%.
And finally you obviously haven't been paying attention, but the HS1 link to the Channel tunnel has left the taxpayer sitting on an extra £4.8 billion of debt. Why won't people like you learn? I can understand people like Cameron wanting this, because it'll be his rich mates wanting to build it, and because the man is utterly clueless. You quote the business case numbers as though they were fact - they aren't. They are estimates, and projections, if you like guesses. No commercial financier would touch HS2 if their return were dependant upon the accuracy of the numbers. But tax payers? We've got twat MP's top make the decision on our behalf, and everybody knows public money is free.
What's your excuse for thinking that HS2 makes sense?
