I believe that the case for HS2 is so overwhelming that it is not a question of why we are doing it, but why we are not doing it quicker, although I realise that people would not get that impression from the debate. I congratulate the right hon. Member for Chesham and Amersham (Mrs Gillan) on obtaining the debate. She is a doughty fighter for her constituents, and no doubt had she achieved her ambition to represent Manchester she would have been just as doughty a fighter for HS2 as she is against it now.
Reading the report of the House of Lords Economic Affairs Committee and listening to the debate have made it clear to me why this country is so appallingly bad at major infrastructure projects. How many new arterial routes have we had in this country in the past 40 years? The answer is one—leaving the country, as part of an international treaty: HS1. The real reason we need HS2, going both west and east of the country as it gets further north, is that the motorway system is clogged.
The M1 and M6 are congested a great deal of the time. The west and east coast railways are often congested and are reaching their limits. There is not enough capacity on the rail system for freight. HS2, with the investment of possibly £50 billion, will free up capacity on all those systems. People say that alternatives have not been looked at, but do they believe that there is any possibility that we will build new motorways west and east of this country? There is simply no chance. HS2 is the only way to free up that capacity.
Certainly some things can be improved in this country. It is interesting, in terms of both cost and speed, that on the high-speed route from Tours to Bordeaux the civil engineering work on 200 km of line was achieved—started and finished—in two years. There is a lot we can learn, to lower the cost and improve the speed of what we do. The arguments are big.
