Well its speed and capacity. Essentially they HSR will be running at gradients of up to 1 in 55, about 40% less space than a 6 lane highway and 40% more capacity, at speeds 3-4 times quicker than roads, and better than air under 300-400miles - all with relatively low environmental impact.
I'm pleased to see they have including construction and operating emissions (including the trains), which are so rolled out as a defence against not building these sorts of things and it works out 5-7 g co2 per seat km and assumed 10-15g pass km. Making a likely grand total of around 15-30 g co2 per passenger km - which is considerably lower than car and air, even without indirect emissions and other effects - which I hope the DFT include in future schemes for other modes. Total land take is around 4.5 miles square, which is a bit more than Stansted expansion.
They only fly in the ointment is the cost, but then at £2 bn per year of public money (remember some of it is private and its likely to make an operating profit as most HSR lines do), its actually 0.3% of public spend over 10 years. Considering the economic advantages for the Midlands and the north, I would hope people will back it. Ultimately it will need public and political support, however I can see vested interests lobbying against it even though it would actually improve things for them to.
