Peter Mandelson is one of a growing number of sceptics about the wisdom of proceeding with HS2.
See the following article: http://www.independe...on-8685062.html.
I've been sceptical all along. There seems to be some evidence that high speed rail links simply make it easier for organisations in capital cities to avoid decentralising to the provinces.
One of the best examples seems to be the Madrid-Seville HS link, which, on balance, appears to have sucked investment out of Seville that might otherwise have gone there.
Even then, HS2 may arguably benefit Birmingham, Manchester, Sheffield and Leeds. But not anywhere else.
I just don't think the cost and the disruption is worth the money, which could be far better spent elsewhere, not least on improving the rest of the railway system.
